Maxim Integrated MAX809LEUR T
- Part Number:
- MAX809LEUR T
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3269574-MAX809LEUR T
- Description:
- IC MPU RESET CIRC 4.63V SOT23
- Datasheet:
- MAX809LEUR T
Description
The MAX803/MAX809/MAX810 are microprocessor (µP) supervisory circuits that monitor power supplies in µP and digital systems. They provide reliability and cost-effectiveness by eliminating external components and adjustments when used with 5V, 3.3V, 3.0V, or 2.5V powered circuits.
These circuits assert a reset signal when the Vcc supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after Vcc has risen above the reset threshold. Reset thresholds are available for various supply voltages.
The MAX803 has an open-drain output stage, while the MAX809/MAX810 have push-pull outputs. The MAX803's open-drain RESET output requires a pullup resistor that can be connected to a voltage higher than Vcc. The MAX803/MAX809 have an active-low RESET output, while the MAX810 has an active-high RESET output. The reset comparator ignores fast transients on Vcc, and the outputs are guaranteed to be in the correct logic state for Vcc down to 1V.
Features
