MAX16021PTER+

Supervisors Overview

The MAX16021PTER+ is a low-power supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a single monitored input with a factory-set reset threshold for voltages ranging from 1.1V to 5V. The device operates within a supply voltage range of 1.53V to 5.5V and consumes only 1.2µA of quiescent current. It includes a manual reset input, a watchdog timer, and a battery backup switch. The IC provides active high and active low push-pull outputs with a reset delay time of 215 ms. It is housed in a TQFN-EP-16 package and supports power-failure detection.

Supervisors Feature Summary

• Provides robust power-system supervision for safety-critical automotive applications
• Integrates a watchdog timer and battery backup switch for enhanced system reliability
• Features manual reset capability with configurable output states

Supervisors Applications

• Safety-critical automotive power system monitoring
• General-purpose voltage supervision in embedded systems
• Battery-powered devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix (TER) against the official datasheet to confirm pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status as distribution may vary by region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any specific handling or storage instructions provided in the product documentation.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. It is suitable for designs needing a fixed threshold without external resistor networks. Consider the TQFN-EP-16 package for space-constrained PCB layouts. Evaluate the 1.2µA quiescent current against total system power budgets. Verify that the 215ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This part belongs to the MAX16021L series of supervisory circuits designed for low-power applications. It is part of Analog Devices' portfolio of power management ICs focused on system protection. The device complements other supervisors in the family by offering combined overvoltage/undervoltage detection with watchdog features. It is intended for use in environments where reliable voltage monitoring is critical for system integrity.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the MAX16021 family, such as MAX16021PTET+. Verify that alternative parts maintain the same 1.1V to 5V monitoring range and 1.2µA current consumption. Ensure the replacement package matches the TQFN-EP-16 footprint if board space is limited.
