Part UM803
Description 3-Pin Microprocessor Reset Circuits
Feature UM803 3-Pin Microprocessor Reset Circui ts UM803 SOT323/SOT23-3 General Descrip tion The UM803 is a microprocessor (μ P) 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 w hen used with +5V, +3.
3V, +3.
0V or +2.
5 V powered circuits.
The circuit perfor ms a single function: it asserts a rese t signal whenever the VCC supply voltag e declines below a preset threshold, ke eping it asserted for at least 140ms af ter VCC has risen above the reset thres hold.
