MAX6888RETE+

Supervisors Overview

The MAX6888RETE+ is a hex/quad power-supply supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.8 V and draws a typical operating current of 900 uA. The device features four monitored inputs with identical thresholds: overvoltage thresholds are set at 673 mV for all channels, while undervoltage thresholds are fixed at 527 mV. It includes a manual reset input and an integrated watchdog timer. The component is housed in a TQFN-16 package and supports surface-mount installation.

Supervisors Feature Summary

• Provides simultaneous monitoring of multiple power rails using configurable or fixed threshold detectors.
• Integrates a watchdog timer function to detect software malfunctions and trigger system recovery.
• Supports manual reset control via a dedicated input pin for external system management.

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Watchdog timer implementation for microprocessor reset protection
• Voltage monitoring in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold settings and package type. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check RoHS compliance documentation if required for your assembly process.

Supervisors Selection Notes

Select this component when hex or quad voltage supervision is required with a single IC. Ensure the fixed 673 mV overvoltage and 527 mV undervoltage thresholds align with your target rail specifications. Consider the TQFN-16 package size for board space constraints. Verify that the 900 uA quiescent current fits your power budget requirements.

Supervisors Part Context

This part belongs to the MAX6888 series of supervisory circuits from Maxim Integrated, now part of Analog Devices. The series offers various configurations for monitoring power supplies in portable and industrial applications. The RETE+ suffix indicates a specific threshold configuration and tape-and-reel packaging option within the broader product family.
