Pin Configuration

PT7M1233/1233A

Supervisory Circuit

The PT7M1233/1233A series are designed to monitor power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments.

The devices perform a single function assert a reset signal whenever the VCC supply voltage falls below a preset threshold. Reset remains asserted 200ms after VCC has risen above the reset threshold.

PT7M1233/1233A are bidirectional output, allowing it to monitor a pushbutton on the reset output.
