CMOS IC
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 VCC supply voltage declines below a preset threshold,
keeping it asserted for at least 140ms after VCC has 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
V
V
CC, and outputs are guaranteed to be in the correct logic state for
CC down 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.
