UNISONIC TECHNOLOGIES CO., LTD UTC812 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, +3.0Vpowered 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.
