Supervisor IC for battery-backed system monitoring
The MAX793TCSE+: It provides both active-high and active-low reset outputs, configurable as open-drain or push-pull, giving the designer flexibility to interface with different microcontroller reset input structures. The reset timeout is a minimum of 140 ms, ensuring the system has adequate time to stabilize after power-up before the processor begins executing code.
Threshold, timeout, and temperature range
The 3.075V threshold is suitable for monitoring 3.3V rails, asserting reset before the supply falls below the minimum operating voltage of typical 3.3V logic.
