UM803 Product details

Description

The UM803 is a microprocessor (μP) supervisory circuit used to monitor the power supplies in μP and digital systems.It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V or +2.5V powered circuits.The 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 thres
