TS3809/3810 Series

Microprocessor Reset Circuit

SOT-23

2. (RESET)

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.
