Overview
The MAX6778LT+T is a low-power, 1%-accurate battery monitor from the Maxim Integrated family. It features a single battery monitor with external inputs for rising and falling thresholds, allowing for external hysteresis control. The device operates within a supply voltage range of 1V to 5.5V and is available in an ultra-small 6-pin µDFN package (1.0mm x 1.5mm). It supports alkaline, lithium-ion, nickel cadmium, and nickel metal hydride battery types.
Feature Summary
- Provides a single low-battery output with externally adjustable hysteresis via dedicated threshold inputs.
- Offers flexible interface options with both open-drain and push-pull output configurations available.
- Designed for low-power applications monitoring single-cell or multi-cell power sources.
Applications
- Monitoring single lithium-ion cells
- Monitoring multicell alkaline power sources
- Monitoring multicell NiCd/NiMH power sources
Procurement Notes
Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm the specific suffix 'LT' corresponds to the µDFN-6 package variant. Ensure compatibility with system voltage requirements between 1V and 5.5V. Check for RoHS compliance documentation if required by procurement policy. Validate that external components for threshold setting are included in the design.
Selection Notes
Select this component when external hysteresis control is required for noise immunity. Choose over fixed-hysteresis variants like MAX6775/76 if programmable thresholds are necessary. Consider the µDFN-6 package size constraints against SC70 alternatives. Verify that the single-channel architecture meets the system's monitoring needs without requiring dual outputs.
Part Context
Part of the MAX6775–MAX6781 family of low-power battery monitors. Distinguished by its single-channel design with external threshold inputs, unlike the factory-set hysteresis versions. Manufactured by Analog Devices / Maxim Integrated.
Replacement Considerations
Consider MAX6775, MAX6776, or MAX6777 for fixed hysteresis options. Evaluate MAX6779/MAX6780 for dual-channel requirements. Verify package compatibility if substituting with SC70 variants.
