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

whenever the V_CCsupply voltage declines below a preset threshold,

keeping it asserted for at least 140ms after V_CChas risen above the

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

_CC, and outputs are guaranteed to be in the correct logic state for

_CCdown to 1V.

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

intelligent instruments, critical microprocessors, microcomputer

power monitoring, portable, or battery-powered equipments and

automotive device.

FEATURES

* Supply Current: 10µA
