The Diodes Incorporated APX809-40SAG-7 is a microprocessor supervisory circuit designed for monitoring power supplies in digital systems. It features a precise monitoring of a 4V power supply and asserts an active low reset signal when the VCC supply voltage declines below a preset threshold, maintaining the reset for at least 140ms after VCC has risen above the threshold.
This device is ideal for critical microprocessor and microcontroller power monitoring applications. It offers a low supply current of 30µA typical and is fully specified over temperature. The reset output is guaranteed to be valid down to 1V VCC.
The APX809-40SAG-7 is available in a compact SOT-23-3 surface mount package, making it suitable for space-constrained designs. It is also RoHS3 compliant, lead-free, and halogen-free.
Key features include push-pull active low reset output, a 140ms minimum reset timeout, and operation guaranteed down to 1V VCC. The circuit is designed to ignore fast transients on VCC.
