MAX6780LTB+

Overview

The MAX6780LTB+ is a dual-channel, low-power battery monitor from the Analog Devices Maxim Integrated portfolio. Designed for portable applications, it provides accurate monitoring of single or multi-cell power sources including lithium-ion, alkaline, NiCd, and NiMH batteries. The device operates within a supply voltage range of 1V to 5.5V and features fixed or resistor-adjustable hysteresis to eliminate output chatter caused by input noise or terminal voltage recovery. It is housed in a compact 6-µDFN package.

Feature Summary

• Dual low-battery outputs for comprehensive power status indication
• Resistor-adjustable hysteresis prevents output chatter due to noise
• Supports multiple battery chemistries including Li+, alkaline, and NiMH

Applications

• Portable electronic devices requiring battery level monitoring
• Single or multi-cell alkaline and NiCd/NiMH power source management
• Lithium-ion cell protection circuits

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to limited availability or obsolescence. Confirm package integrity and pin alignment against official datasheet specifications before integration. Ensure compliance with RoHS directives and check for specific manufacturing date codes if long-term reliability is critical for the application design.

Selection Notes

Select the MAX6780LTB+ when dual independent battery monitoring is required in space-constrained designs. Consider its adjustable hysteresis feature for noisy environments where stable switching is essential. Evaluate compatibility with target battery types such as lithium-ion or multi-cell alkaline packs to ensure optimal threshold settings and system efficiency.

Part Context

This component belongs to the MAX6775–MAX6781 series of low-power, 1%-accurate battery monitors. These devices are engineered for ultra-small form factors using µDFN and SC70 packages. The series offers flexibility with single or dual outputs and supports various battery chemistries, making it suitable for a wide range of portable consumer electronics and industrial handheld instruments.

Replacement Considerations

Compatible substitutes within the same family include the MAX6779LTB+T and MAX6781LTB+T. Verify that alternative parts match the dual-channel configuration and package dimensions. Check for equivalent operating voltage ranges and hysteresis capabilities to ensure functional parity in existing circuit designs.
