MICROPROCESSOR RESET IC

DESCRIPTION

The UTC UTC812 is a microprocessor (µP) reset circuit designed

to monitor the power supplies in µP and digital systems.

The UTC UTC812 has push-pull output and active-low RESET

output.

This device provides customers with perfect system reliability and

low cost which are achieved by to no external component

requirement and adjustments when used with +5V, +3.3V, +3.0V-

powered circuits.

This circuit performs a single function: it asserts a reset signal

reset threshold. Reset thresholds suitable for operation with a variety

of supply voltages are available.

The reset comparator can be used to ignore fast transients on

In applications, the UTC812 is suitable for computers, controllers,

intelligent instruments, critical microprocessors, microcomputer

power monitoring, portable, or battery-powered equipments and

automotive device.
