Analog Devices ADM1232 Microprocessor Supervisory Circuit Datasheet
The ADM1232 is a microprocessor monitoring circuit designed to monitor supply voltage, detect microprocessor lock-ups, and handle external interrupts. It serves as a superior, pin-compatible upgrade for the MAX1232 and Dallas DS1232LP/DS1232 devices. The circuit is available in four different packages: 8-lead microSOIC, 8-lead PDIP, 16-lead wide SOIC, and 8-lead narrow SOIC.

From: Analog Devices ADM1232 Microprocessor Supervisory Circuit Datasheet
What supply voltage options does the ADM1232 support?
The device can operate at 4.5 V, 5.0 V, or 5.5 V supply voltages.
How long must the PB RESET be held low to guarantee a reset?
PB RESET must be held low for a minimum of 20 ms to guarantee a reset.
How is the voltage‑tolerance level selected?
Connect the TOLERANCE pin to GND for a 5 % tolerance (trip at ~4.75 V) or to VCC for a 10 % tolerance (trip at ~4.5 V).
