MAX6703AZKA+

Supervisors Overview

The MAX6703AZKA+T is a triple-channel micropower voltage supervisor in an SOT-23-8 package. It monitors three independent supply rails with adjustable thresholds ranging from 2.38 V to 4.5 V. The device features a manual reset input, a watchdog timer, and an open-drain output. Operating at 12 µA quiescent current, it supports a maximum supply voltage of 5.5 V across a -40°C to +125°C temperature range.

Supervisors Feature Summary

• Triple-channel monitoring for independent power rail supervision
• Integrated watchdog timer for system reliability
• Manual reset capability via dedicated input pin
• Ultra-low quiescent current consumption

Supervisors Applications

• Portable electronic devices requiring multi-rail power management
• Embedded systems needing hardware-based fault detection
• Industrial control units operating in extreme temperatures
• Battery-powered equipment prioritizing low standby current

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as variations like 'T' indicate tape-and-reel packaging while others may differ. Confirm RoHS compliance status through manufacturer certificates. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required within a compact footprint. Ensure the adjustable threshold range covers the specific supply voltages under surveillance. Verify that the open-drain output configuration aligns with the downstream logic interface requirements.

Supervisors Part Context

Part of the MAX6701–MAX6708 series designed for micropower applications. These supervisors offer flexible threshold adjustments and integrated safety features like watchdog timers. The family targets space-constrained designs where low power consumption and high reliability are critical operational parameters.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts maintain identical pinout configurations and electrical characteristics to avoid redesign efforts.
