MAX16021PTES+

Supervisors Overview

The MAX16021PTES+ is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.53 V to 5.5 V and features a threshold voltage of 3.1 V. The device includes a manual reset input, a watchdog timer, and battery backup switching capabilities. It provides active high, active low, and push-pull output types with a reset delay time of 215 ms. Designed for surface mount installation in a TQFN-EP-16 package, it supports power failure detection and functions across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer and battery backup switch for comprehensive system monitoring
• Supports multiple output configurations including active high, active low, and push-pull
• Features manual reset capability for user-initiated system control

Supervisors Applications

• Portable equipment requiring low-power supervision
• Battery-powered systems needing backup switching
• Embedded controllers utilizing watchdog protection

Supervisors Procurement Notes

Verify the specific suffix PTES against official datasheets to confirm package type and thermal pad configuration. Confirm RoHS compliance status through manufacturer documentation. Ensure the component source is authorized to avoid counterfeit risks. Check current availability as distribution status may vary. Validate that the ordering information matches the required electrical specifications for your design.

Supervisors Selection Notes

Select this component when a single-input supervisory circuit with integrated watchdog functionality is required. Consider the 1.53 V minimum operating voltage for compatibility with lower voltage rails. Evaluate the 215 ms reset delay against system startup timing requirements. The TQFN-EP-16 package offers a compact solution for space-constrained designs.

Supervisors Part Context

This part belongs to the MAX16021L series of low-power supervisory circuits. It is designed to monitor voltage levels and provide reset signals to protect electronic systems from power-related faults. The inclusion of a watchdog timer distinguishes it from basic voltage supervisors, offering enhanced reliability for microprocessor-based applications.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the MAX16021 family. Verify pinout and electrical parameter compatibility before replacing. No direct public substitute part numbers are confirmed in the provided data.
