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_CCreturns 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.
