General Description

The FM1233A is a supervisor circuit that monitors a microprocessor power supply or other system voltage and issues a reset pulse when a fault condition exists.

Several different threshold voltages are offered to accommodate 3.3V and 3.0V systems with different tolerances.

Key Features

a precision temperature-compensated voltage reference and comparator. When VCC falls to the threshold voltage, a RESET pulse is issued, holding the output in the active state. When power rises above VTH, the reset remains asserted for a minimum period (tRST) to allow the system clock and other circuits to stabilize. The reset output of FM1233A is of open-drain active low type. The FM1233A also can monitor a switch closure on its output, enabling it to recognize an external reset from a pushbutto.
