About this manual

The TS803/TS803R are microprocessor (UP) supervisory circuits designed to monitor power supplies in UP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, or +3.0V powered circuits. These circuits assert 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.
