DESCRIPTION
The DS1232 MicroMonitor? Chip monitors three vital conditions for a microprocessor: power supply,
software execution, and external override. First, a precision temperature-compensated reference and
comparator circuit monitors the status of V CC . When an out-of-tolerance condition occurs, an internal
power fail signal is generated which forces reset to the active state. When V CC returns to an in-tolerance
condition, the reset signals are kept in the active state for a minimum of 250 ms to allow the power supply
and processor to stabilize.
