Unisonic Technologies UIC812
UIC812 is microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits. The UTC UIC812 also provides a debounced manual reset input.| Part No. | UIC812 |

DESCRIPTION
The UTC These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140 ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The UTC UIC812 has an active-low RESET output stage, The UTC UIC812’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. Low supply current makes the UTC UIC812 ideal for use in portable equipment. 4 5 1 23 SOT-23-5 (JEDEC TO-236) 3 4 2 1 SOT-143●
