MAX6348UR44-T Description

Short technical summary and product information.

The MAX6348UR44-T is a microprocessor supervisory circuit from Analog Devices, designed to monitor power supply voltages in digital systems. It provides an active-low, open-drain reset output that asserts when the VCC supply voltage declines below a preset threshold, maintaining the reset for at least 100ms after VCC has risen above the threshold. This device is factory-set to monitor a 4.4V supply and operates over a temperature range of -40°C to 85°C.

 

Key features include a minimum reset timeout of 100ms, monitoring of single voltage rails, and a low typical supply current of 0.5µA. The circuit is designed to ignore fast transients on VCC, ensuring reliable operation. It is available in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained applications.

 

This supervisory circuit is ideal for critical µP and µC power monitoring in portable and battery-powered equipment, computers, intelligent instruments, and controllers. Its robust design and low power consumption contribute to excellent circuit reliability and low cost by eliminating external components and adjustments.
