MAX16021PTET+

Supervisors Overview

The MAX16021PTET+ is a low-power microprocessor 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 fixed threshold voltage of 3.1 V for monitoring input lines. The device provides manual reset capability, includes an integrated watchdog timer, and supports battery backup switching functions. It offers multiple output types including active high, active low, and push-pull configurations with a reset delay time of 215 ms. Designed for surface mount installation in TQFN-EP-16 packages, it ensures reliable system supervision across industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated fault recovery
• Supports battery backup switching for continuous monitoring
• Provides configurable output polarity options

Supervisors Applications

• Low-power microprocessor systems requiring voltage supervision
• Industrial control units needing watchdog functionality
• Portable devices utilizing battery backup circuits

Supervisors Procurement Notes

Verify the specific suffix 'PTET+' against official manufacturer documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check authorized distributor availability since some listings indicate limited stock or discontinuation risks. Ensure the component matches the required TQFN-EP-16 footprint for PCB integration.

Supervisors Selection Notes

Select this component when a single-supply supervisor with watchdog and backup capabilities is required. Compare quiescent current specifications against other family members if ultra-low power consumption is critical. Verify that the 3.1 V threshold aligns with the target logic voltage levels. Consider the TQFN-EP-16 package size constraints relative to available board space.

Supervisors Part Context

This part belongs to the MAX16021L series of low-power supervisory circuits designed for embedded applications. It shares functional similarities with the MAX16020 but offers distinct output configurations and power management features. The series targets cost-sensitive designs requiring robust reset generation without external components.

Supervisors Replacement Considerations

Consult official cross-reference guides for direct pin-compatible alternatives. Verify electrical parameters such as threshold voltage and reset delay times before substitution.
