MAX6703ZKA

Supervisors Overview

The MAX6703ZKA is a triple uPower supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three independent voltage inputs and provides reset signals when thresholds are exceeded. The device operates within a supply voltage range of up to 5.5V and features an active low, open-drain output. It includes manual reset functionality and a watchdog timer for system reliability. The component is housed in an SOT-23-8 package and supports surface mount installation. It is designed for low-power applications with a typical operating current of 12 µA.

Supervisors Feature Summary

• Triple channel voltage supervision for monitoring multiple power rails simultaneously
• Integrated watchdog timer to detect software malfunctions and trigger system recovery
• Manual reset input allows external control over the reset state for initialization sequences

Supervisors Applications

• Portable battery-powered electronic devices requiring efficient power management
• Embedded systems needing reliable voltage supervision for microcontrollers
• Industrial control units utilizing watchdog timers for fault detection

Supervisors Procurement Notes

Verify the exact suffix and manufacturer lot codes against official Analog Devices documentation before procurement. Confirm RoHS compliance status and lead times directly with authorized distributors as availability may vary. Ensure the selected variant matches the required threshold voltages and package specifications for your design.

Supervisors Selection Notes

Select this component when triple voltage monitoring is required in a compact SOT-23-8 footprint. Consider the 12 µA quiescent current for battery-sensitive designs. Verify that the open-drain output configuration aligns with the downstream logic requirements. Check if the integrated watchdog and manual reset features meet the specific system safety and initialization needs.
