MAX6432FJUS-T

Overview

The MAX6432FJUS-T is a low-power, single/dual-level battery monitor manufactured by Maxim Integrated. It features a SOT-143 (SOT143-4) surface-mount package with four pins. The device supports multiple battery chemistries and includes hysteresis for stable operation. It functions as a power supply support circuit within the BICMOS technology family.

Feature Summary

• Monitors battery voltage levels with dual-level detection capabilities
• Incorporates internal hysteresis to prevent output oscillation during threshold transitions
• Designed for multi-chemistry battery applications without external component adjustments

Applications

• Battery management systems in portable electronics
• Single or dual-level voltage monitoring for battery-powered devices
• Power supply support circuits requiring low quiescent current

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as sources indicate non-compliance for this specific part number variant. Ensure the manufacturer is identified as Maxim Integrated or Analog Devices Inc. prior to ordering.

Selection Notes

Select this component when dual-level battery monitoring with hysteresis is required in a compact SOT-143 footprint. It is suitable for applications supporting various battery chemistries where fixed thresholds are acceptable. Verify that the operating temperature range and package type meet system constraints.

Part Context

This part belongs to the MAX6432 series of low-power battery monitors. It is distinct from the MAX646x family which offers different pin counts and reset functionalities. The FJUS-T designation specifies the thermal grade, package style, and reel packaging format.

Replacement Considerations

Check for MAX6432FIUS+T for leaded alternatives. Verify compatibility with other MAX6432 variants based on threshold voltages and package dimensions before substitution.
