TS3809/3810 Series
Microprocessor Reset Circuit
1/7
Version: C07
SOT-23
General Description
The TS3809/3810 series are used for microprocessor (P) supervisory circuits to monitor the power supplies in P
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 VCC supply voltage declines below a
preset threshold, keeping it asserted for at least 200ms after VCC has 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 VCC, and the outputs are guaranteed to be in the correct
logic state for VCC down to 1.0V. Low supply current makes TS3809/3810 series ideal for use in portable equipment.
