MAX6394US310D3+T Description

Short technical summary and product information.

The MAX6394US310D3+T is a single-channel microprocessor supervisory circuit designed by Analog Devices for monitoring power supplies in digital systems. It provides a reset signal when the VCC supply voltage drops below a preset threshold or when a manual reset is asserted. The reset signal remains active for a programmed interval after the voltage recovers or the manual reset is deasserted.

 

This device offers high accuracy with ±1.0% threshold accuracy over the operating temperature range of -40°C to +125°C. It features factory-trimmed reset threshold voltages ranging from 2.4V to 4.8V, with this specific part set to 3.102V. Several reset timeout periods are available, including a minimum of 105ms for this variant.

 

The MAX6394US310D3+T is housed in a compact SOT-143-4 surface-mount package. Its open-drain RESET output can be pulled up to a voltage higher than VCC. With a low supply current of 5μA, it is suitable for portable and battery-powered equipment. Applications include computers, controllers, intelligent instruments, and critical μP and μC power monitoring.
