MAX16020PTET+

Supervisors Overview

The MAX16020PTET+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.1 V for monitoring a single input. The device provides manual reset capability, includes an integrated watchdog timer, and supports battery backup switching. It offers active high, active low, and open drain output types with a reset delay time of 215 ms. Designed for surface mount installation in a TQFN-16 package, it functions reliably across temperatures from -40°C to +85°C while consuming only 3.4 µA of quiescent current.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset functionality for robust system control
• Supports battery backup switching to maintain data integrity during power transitions
• Provides flexible output configurations including active high, active low, and open drain options

Supervisors Applications

• Low-power microprocessor systems requiring voltage supervision
• Portable electronic devices utilizing battery backup mechanisms
• Industrial control circuits needing watchdog timer protection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check current availability as the part may be subject to limited supply conditions. Ensure packaging specifications match design integration needs. Validate that the TQFN-16 footprint aligns with existing PCB layouts.

Supervisors Selection Notes

Select this component when a single-channel supervisor with watchdog and manual reset is required. Consider the 3.1 V threshold against target rail voltages. Evaluate the 3.4 µA quiescent current against strict power budgets. Verify compatibility between available output types and downstream logic levels. Assess thermal performance within the specified operating temperature range.

Supervisors Part Context

This supervisory circuit belongs to the MAX16020 series designed for embedded applications. It addresses common failure modes in microprocessor systems by detecting under-voltage conditions. The inclusion of a watchdog timer distinguishes it from basic voltage monitors. Its compact TQFN-16 package facilitates integration into space-constrained designs.

Supervisors Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Ensure replacement parts maintain identical threshold voltages and package dimensions. Verify functional equivalence regarding watchdog timer operation and reset delay times.
