LM3420AM5-12.6

Battery Chargers Overview

The LM3420AM5-12.6 is a charge controller IC designed for lithium-ion battery packs consisting of three series-connected cells. It operates within an input voltage range of 8.4 V to 16 V and supports a maximum charging current of 5 A. The device implements a standard constant-current/constant-voltage (CC/CV) charging profile with thermal regulation to manage heat dissipation during operation.

Battery Chargers Feature Summary

Implements constant-current and constant-voltage charging algorithms for multi-cell lithium-ion batteries
Integrates thermal regulation to reduce charging current when die temperature exceeds safe limits
Supports programmable charging termination based on timer or current threshold

Battery Chargers Applications

Charging lithium-ion battery packs with three series-connected cells
Portable electronic devices requiring multi-cell battery management
Industrial equipment utilizing 12 V nominal lithium-ion power sources

Battery Chargers Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm package compatibility with SOT-23-5 footprints. Review datasheet revisions for any functional updates. Ensure supply chain alternatives are identified due to end-of-life status. Validate pinout alignment with existing circuit designs.

Battery Chargers Selection Notes

Select this component only for applications requiring three-cell lithium-ion battery charging. Verify that the system input voltage remains within the specified 8.4 V to 16 V range. Ensure the required charging current does not exceed 5 A. Consider thermal management requirements given the integrated regulation feature. Evaluate alternative active components if long-term availability is critical.
