MAX6432MRUS

Overview

The MAX6432MRUS is a low-power, multi-chemistry battery monitor IC designed for single or dual-level monitoring applications. It supports two-cell battery systems and features hysteresis to prevent output chatter during threshold transitions. The device operates within a temperature range of -40°C to +85°C (TA) and is housed in a surface-mount SOT143-4 package. It provides TTL-compatible inputs for interface with digital logic.

Feature Summary

• Multi-chemistry battery monitoring capability for versatile cell type support
• Integrated hysteresis mechanism to ensure stable output states
• TTL-compatible input logic levels for direct microcontroller interfacing

Applications

• Two-cell battery system management
• Embedded processing power monitoring
• Industrial networking equipment
• Internet of Things (IoT) devices

Procurement Notes

Verify the specific suffix (e.g., +T) against the required reel quantity and tape-and-reel specifications. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated as per current corporate structure. Ensure the package type corresponds to SOT143-4 for proper PCB footprint compatibility.

Selection Notes

Select this component when monitoring two-cell battery configurations requiring low quiescent current. The SOT143-4 package is suitable for space-constrained designs. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.

Part Context

This part belongs to the MAX643x series of battery monitors from Maxim Integrated, now part of Analog Devices. These components are engineered for portable electronics where power efficiency and reliable voltage threshold detection are critical. The MRUS variant specifically denotes the SOT143-4 surface-mount package configuration.

Replacement Considerations

Check for MAX6432MRUS+T for tape-and-reel packaging variants. Verify cross-reference availability with other single/dual-level battery monitors if supply constraints exist.
