The TS803/TS803R are 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. 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 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The TS803/TS803R are open-drain outputs. The TS803/TS803R have an active low RESET output, while the TS803/TS803R has an active high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the output is guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the TS803/TS803R ideal for use in portable equipment.
