Overview
UM805/811/812
4-Pin μP Voltage Monitors with Manual Reset Input UM805/811/812 SOT143
General Description
The UM805/811/812 are low-power microprocessor (μP) supervisory circuits used to monitor 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-powered or 3V-powered circuits.
The UM805/811/812 also provide a debounced manual reset input.
These devices perform a single function: They assert a reset signal whenever the VCC supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold.
Reset thresholds are ava...
