TS3809 Series Microprocessor Reset Circuit

PublishTime：2022-05-23

■General Description
●The TS3809 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-CC supply voltage declines below a preset threshold, keeping it asserted for at least200ms after V-CC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. TS3809 series have push pull outputs. TS3809 series has an active low 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-CC down to 1.0V. Low supply current makes TS3809 series ideal for use in portable equipment.
