MAX16001ATE+

The MAX16001ATE+ is a low-voltage, quad-voltage microprocessor supervisor from Analog Devices, housed in a compact 16-TQFN package. This device is engineered to provide supervisory functions for complex multivoltage systems, monitoring up to four distinct voltage rails.

Key features include adjustable voltage thresholds that can monitor voltages down to 0.4V, alongside fixed thresholds for common voltages like 5V, 3.3V, 2.5V, and 1.8V. The supervisor provides an active low reset output that asserts when monitored voltages fall below their respective thresholds. It also includes a watchdog timer with a typical timeout period of 1.6 seconds, which can assert a reset if the system becomes unresponsive.

The MAX16001ATE+ offers open-drain outputs with internal 30μA pullups, reducing the need for external components. The reset timeout is adjustable or selectable, with a minimum of 140ms. Other functionalities include a manual reset input and a margin enable function for testing purposes.

This supervisor is suitable for applications requiring robust voltage monitoring in systems such as storage equipment, servers, and networking/telecommunication equipment. Its operating temperature range is -40°C to 125°C (TA), and it is supplied in a 16-TQFN (4x4) package.
