Microprocessor Reset Circuit
1/6
Version: A07
SOT-23
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.
