MAX16021PTEV+

Supervisors Overview

The MAX16021PTEV+ is a low-power voltage 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 with an overvoltage threshold of 3.19 V. The device draws 1.2 uA of operating supply current and includes a manual reset input, watchdog timer, and battery backup switch. It provides active high, active low, and push-pull outputs with a reset delay time of 215 ms. Designed for surface mount installation, it is housed in a TQFN-EP-16 package and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

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

Supervisors Applications

• Portable equipment requiring low power consumption
• Battery-powered systems utilizing backup switches
• Embedded controllers needing watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix PTEV+ against the official datasheet to confirm the 16-TQFN package and exposed pad configuration. Ensure the required threshold voltage aligns with the 3.1 V specification. Confirm that the operating temperature range of -40°C to +85°C meets your environmental requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and backup features is required. It is suitable for applications demanding low quiescent current and flexible output polarity options. Consider the TQFN-EP-16 package constraints and thermal dissipation capabilities relative to your board layout and power budget.

Supervisors Part Context

This part belongs to the MAX16021L series of supervisory circuits designed for monitoring single voltage rails. It complements other Maxim Integrated PMIC solutions by providing essential reset generation and system health monitoring functions in a compact form factor suitable for space-constrained portable designs.

Supervisors Replacement Considerations

Check for MAX16021LTET+ as a potential alternative with similar specifications but potentially different packaging or tape-and-reel availability. Verify pin compatibility and electrical parameters before substitution.
