• Lithium polymer battery protection circuits
• Portable electronic devices requiring cell balancing
• Medical equipment with single-cell power sources

Battery Management Procurement Notes

Verify the specific suffix 'AAK' against official ABLIC documentation to confirm exact electrical characteristics and pinout compatibility. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may affect long-term supply. Ensure the selected variant matches the required thermal and voltage specifications for the target application environment.

Battery Management Selection Notes

Select this component when active balancing is required for single-cell configurations. Compare the 1.2 µA operating current against system sleep requirements. Verify that the SOT-23-6 package fits the PCB layout constraints. Ensure the 5 V maximum operating voltage aligns with the highest expected cell voltage plus any transient spikes in the circuit design.

Battery Management Part Context

This part belongs to the S-8249 series of battery management ICs from ABLIC. The series focuses on integrated protection and balancing solutions for portable electronics. The S-8249AAK variant specifically addresses single-cell needs, distinguishing itself from multi-cell counterparts like the S-8252 series. It complements other ABLIC PMIC offerings for comprehensive power management.

Battery Management Replacement Considerations

Check for direct substitutes within the S-8249 family, such as the S-8249AAN-M6T1U, ensuring functional equivalence. Verify pin-to-pin compatibility before substitution. Consult ABLIC for updated recommendations if the AAK variant is discontinued.
