MAX6442KAMTRD3+T

Overview

The MAX6442KAMTRD3+T is an ultra-low-power battery monitor and microprocessor supervisor from the MAX6439–MAX6442 family. It features dual low-battery outputs for signaling battery status (OK, Low, Dead) and an independent active-low reset output. The device operates within a supply voltage range of 1 V to 5.5 V and supports single-cell lithium-ion or multicell alkaline/NiCd/NiMH batteries. It utilizes factory-trimmed thresholds with hysteresis and requires no external components.

Feature Summary

• Dual low-battery outputs signal battery health states including OK, Low, and Dead conditions
• Integrated microprocessor supervisor provides an active-low reset output
• Factory-trimmed low-battery threshold combinations eliminate need for external components
• Manual reset function available via push-button input

Applications

• Single-cell lithium-ion battery monitoring systems
• Multicell alkaline, NiCd, or NiMH battery pack supervision
• Microprocessor system power management
• Low-power portable electronic devices requiring battery status alerts
