Analog Devices Inc. ADM705ARZ
- Part Number:
- ADM705ARZ
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3269871-ADM705ARZ
- Description:
- IC SUPERVISOR MPU 4.65 WD 8SOIC
- Datasheet:
- ADM705ARZ
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.
