MAX6430PQUS

Overview

The MAX6430PQUS is a low-power battery monitor IC designed for single or dual-level voltage supervision. It supports multi-chemistry batteries with up to two cells, offering flexible monitoring capabilities. The device operates within a temperature range of -40°C to +85°C and utilizes a surface-mount package. Key electrical parameters include hysteresis features to prevent output chatter during threshold crossings.

Feature Summary

• Supports multi-chemistry battery types including lithium-ion and nickel-based cells
• Provides dual independent voltage monitoring channels for single or two-cell configurations
• Incorporates hysteresis to ensure stable output states during voltage transitions

Applications

• Power distribution systems in medical operating rooms
• Power distribution systems in infant care rooms
• Portable electronic devices requiring reliable battery level indication

Procurement Notes

Verify the specific suffix (e.g., PQUS) against the manufacturer's current datasheet to confirm pinout and package dimensions. Confirm availability status as some listings indicate discontinued status. Ensure compatibility with your system's voltage thresholds before integration.

Selection Notes

Select this component when dual-channel battery monitoring is required for portable applications. Consider its low-power consumption profile for battery-operated devices. Verify that the operating temperature range meets your environmental requirements.

Part Context

This part belongs to the MAX6430 series of battery monitors from Maxim Integrated, now part of Analog Devices. It is designed for applications needing simple, cost-effective voltage supervision without complex communication interfaces.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6430 family. Verify functional equivalence regarding threshold voltages and hysteresis values before substituting.
