Part Overview

Description
The ADM705/ADM706/ADM707/ADM708 microprocessor supervisory circuits are suitable for monitoring 5 V power supplies/batteries and can also monitor microprocessor activity.
The ADM705/ADM706 provide power-supply monitoring circuitry that generates a reset output during power-up, power-down, and brownout conditions. The reset output remains operational with Vcc as low as 1 V. Independent watchdog monitoring circuitry is also provided. This is activated if the watchdog input has not been toggled within 1.60 seconds. In addition, there is a 1.25 V threshold detector to warn of power-failures, to detect low battery conditions, or to monitor an additional power supply. An active low, debounced manual reset input (MR) is also included.
The ADM705 and ADM706 are identical except for the reset threshold monitor levels, which are 4.65 V and 4.40 V, respectively.
The ADM707 and ADM708 provide a similar functionality to the ADM705 and ADM706 and only differ in that a watchdog timer function is not available. Instead, an active high reset output (RESET) is available as well as the active low reset output (RESET). The ADM707 and ADM708 are identical except for the reset threshold monitor levels, which are 4.65 V and 4.40 V, respectively.

  • Mount
    Surface Mount
  • Mounting Type

    Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include: * Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side. * Surface-mount: Component is placed on the surface of the PCB and soldered in place. * Press-fit: Component is pressed into place on the PCB without soldering. * Socket: Component is inserted into a socket on the PCB, allowing for easy replacement. The mounting type is determined by factors such as the component's size, shape, and power requirements.

    Surface Mount
  • Package / Case

    Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

  • Number of Pins

    Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

  • Operating Temperature

    Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

  • Part Status

    Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

  • Technology

    Technology, in the context of electronic components, refers to the specific manufacturing process and materials used to create the component. It encompasses the semiconductor fabrication techniques, such as the type of transistor used (e.g., MOSFET, BJT), the gate oxide thickness, and the interconnect materials. Technology also includes the packaging type, such as surface mount or through-hole, and the leadframe or substrate material. The technology used impacts the component's performance characteristics, such as speed, power consumption, and reliability.

  • Supply Voltage

    Supply Voltage is the voltage required to power an electronic component. It is typically measured in volts (V) and is specified in the component's datasheet. The supply voltage must be within the specified range for the component to function properly. If the supply voltage is too low, the component may not function at all. If the supply voltage is too high, the component may be damaged.

  • Number of Channels

    Number of Channels refers to the number of independent signal paths within an electronic component. It indicates how many separate signals can be processed or transmitted simultaneously. For example, an audio amplifier with two channels can amplify two separate audio signals, while a multi-channel data converter can convert multiple analog signals into digital data. The number of channels is a crucial parameter for determining the component's functionality and application.

  • Operating Supply Current

    Operating Supply Current is the amount of current drawn by an electronic component when it is operating under normal conditions. It is typically measured in milliamps (mA) or microamps (µA). The operating supply current is important because it can affect the power consumption of the component and the overall system. A higher operating supply current will result in higher power consumption, which can lead to overheating and reduced battery life.

  • Nominal Supply Current
    250μA
  • Power Dissipation

    Power Dissipation is the maximum amount of power that an electronic component can safely dissipate without being damaged. It is typically measured in watts (W) and is determined by the component's physical size, material properties, and design. Exceeding the power dissipation rating can lead to overheating, reduced performance, and even component failure.

  • Reset

    Reset is an electronic component parameter that refers to the process of returning a device or system to its initial state. This can be done by applying a specific voltage or signal to the device, or by physically resetting the device. Resetting a device can be used to clear errors, restore default settings, or to start the device over from the beginning.

  • Threshold Voltage

    Threshold Voltage (Vth) is a critical parameter in electronic components, particularly transistors. It represents the minimum voltage that must be applied to the gate terminal of a transistor to turn it on and allow current to flow between the source and drain terminals. Vth determines the sensitivity of a transistor and influences its switching characteristics. A lower Vth results in a more sensitive transistor that turns on with a smaller gate voltage, while a higher Vth makes the transistor less sensitive and requires a larger gate voltage to turn on.

  • Height

    Height, in the context of electronic components, refers to the vertical dimension of the component. It is typically measured in millimeters (mm) or inches (in). Height is an important parameter to consider when designing and assembling electronic circuits, as it affects the overall size and form factor of the device. Components with a smaller height are often preferred for applications where space is limited, such as in portable devices or embedded systems.

    1.5mm
  • Length

    Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.
