MAX16004ATP+T

Supervisors Overview

The MAX16004ATP+T is a low-voltage, quad-/hex-/octal-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors up to six independent voltage inputs and provides reset signals when thresholds are exceeded. The device features an active-low open-drain output, manual reset capability, and an integrated watchdog timer with a fixed 280 ms reset delay. It operates within a supply voltage range of 1.8 V to 5.5 V and supports adjustable or fixed threshold voltages including 1.8 V and 3.3 V variants. Packaged in a TQFN-20 surface-mount format, it ensures reliable system monitoring across industrial temperature ranges.

Supervisors Feature Summary

• Monitors multiple independent voltage rails for system integrity
• Integrates a watchdog timer for processor fault detection
• Provides manual reset input for user-controlled recovery
• Features active-low open-drain reset output compatibility

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Microprocessor reset generation in industrial controllers
• Watchdog timer implementation for safety-critical applications
• Voltage monitoring in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure correct threshold configurations and pinout compatibility. Confirm RoHS compliance status and manufacturing origin through authorized distributors. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage levels is required alongside watchdog functionality. Ensure the available threshold options match the target rail voltages. Consider the TQFN-20 package size constraints and thermal dissipation requirements for the specific application environment.
