MAX16020PTEZ+T

Supervisors Overview

The MAX16020PTEZ+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.1 V to 5.5 V and features a fixed reset threshold of 3.1 V. The device provides a manual reset input, an active high/low/open drain output, and includes a watchdog timer with a reset delay time of 215 ms. It consumes only 3.4 µA of quiescent current and supports battery backup switching. The component is housed in a 16-pin TQFN package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault recovery
• Supports battery backup switching for continuous monitoring
• Provides manual reset capability via dedicated input

Supervisors Applications

• Low-power microprocessor supervision
• Safety-critical automotive applications
• Portable electronic devices requiring extended battery life

Supervisors Procurement Notes

Verify the specific suffix 'PTEZ' against official datasheets to confirm tape and reel packaging and lead-free status. Confirm availability as distribution channels may list limited stock or end-of-life status. Ensure the 3.1 V threshold matches the target application requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.1 V threshold is required for voltage monitoring. The low 3.4 µA current consumption makes it suitable for battery-operated systems. Verify that the TQFN-16 package fits the PCB layout constraints and that the 215 ms reset delay meets the system startup timing specifications.

Supervisors Part Context

This part belongs to the MAX16020 series of supervisory circuits designed for robust power-system management. It is engineered for safety-critical environments, including automotive applications, where reliable voltage monitoring and reset generation are essential for system stability and protection against power anomalies.

Supervisors Replacement Considerations

Check for MAX16020PTET+ variants with different packaging options. Verify compatibility with MAX16020 derivatives offering adjustable thresholds if the fixed 3.1 V limit is insufficient for the new design requirements.
