General Description
The FM1233B 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 5V
systems with different tolerances.
The device 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 for approximately 250 ms to allow the system clock and other circuits
to stabilize. The reset output of FM1233B is of open-drain active low type.
The FM1233B also can monitor a switch closure on its output, enabling it to
recognize an external reset from a pushbutton switch or a µP. In the case of a
switch, the closure will be debounced by circuitry internal to the FM1233B.
