3. VCC

General Description

The TS3809/3810 series are used for microprocessor (µP) supervisory circuits 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, +2.5V powered circuits.

These circuits perform a single function: they assert a reset signal whenever the V_CCsupply voltage declines below a

preset threshold, keeping it asserted for at least 200ms after V_CChas risen above the reset threshold. Reset

thresholds suitable for operation with a variety of supply voltages are available. TS3809/3810 series have push pull

outputs. TS3809 series have an active low RESET output, while the TS3810 has an active high RESET output The

reset comparator is designed to ignore fast transients on V_CC, and the outputs are guaranteed to be in the correct

logic state for V_CCdown to 1.0V. Low supply current makes TS3809/3810 series ideal for use in portable equipment.
