MAX16021PTEM+

Supervisors Overview

The MAX16021PTEM+ is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.53V to 5.5V and features a fixed reset threshold for monitoring standard system voltages including 5V, 3.3V, 3V, 2.5V, and 1.8V. The device provides robust power-system supervision suitable for safety-critical automotive applications. It utilizes a factory-set reset threshold to ensure accurate voltage monitoring across its operational range.

Supervisors Feature Summary

• Provides robust power-system supervision designed for safety-critical automotive applications

• Low-power voltage supervision in embedded electronics

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to potential availability constraints. Confirm package integrity upon receipt as the device uses a TQFN-EP-16 housing. Cross-reference ordering suffixes with official documentation to ensure functional equivalence. Request manufacturer certificates of conformity for automotive-grade compliance requirements before integration into final assemblies.

Supervisors Selection Notes

Select this component when fixed threshold accuracy is required without external resistor programming. The integrated watchdog timer and manual reset capabilities simplify design complexity. Ensure the operating temperature range meets environmental specifications. Consider the low quiescent current for battery-powered or energy-efficient system architectures requiring reliable voltage oversight.

Supervisors Part Context

This part belongs to the MAX16021L series of supervisory circuits. It shares architectural similarities with the MAX16016 and MAX16020, offering comparable functionality for standard voltage rails. The PTEM+ suffix indicates specific packaging and lead-free composition compliant with RoHS standards. It serves as a dedicated solution for power management ICs requiring precise voltage oversight in compact form factors.

Supervisors Replacement Considerations

Direct substitutes include MAX16021LTEM+ and MAX16021LTET+. Verify pin compatibility and thermal performance characteristics before substitution. Ensure replacement parts maintain the same factory-set threshold values to preserve system monitoring accuracy.
