General Description

The TS803/TS803R are microprocessor (µP) supervisory circuit 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 guaranteed to be in the correct logic state for VCC down to 1V. Low supply correct

makes the TS803/TS803R ideal for use in portable equipment.
