General Description

The TS809/810 series 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 TS809/810 series have push pull outputs. The TS809/809R have an active low RESET

output, while the TS810/810R 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 TS809/810 series ideal for use in portable equipment.
