AP9101CAK-ACTRG1

Overview

The AP9101CAK-ACTRG1 is a battery management integrated circuit from Diodes Incorporated, designed for multicell lithium-ion and lithium polymer battery protection. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages between 2.5 V and 4.375 V. The device features a low operating power current of 3 uA and a maximum power dissipation of 250 mW. It is housed in an SOT-25-5 surface-mount package and functions reliably across a temperature range of -40 C to +85 C.

Feature Summary

• Provides comprehensive protection against overcharge, overdischarge, and abnormal current conditions by controlling external MOSFET switches.
• Integrates a fixed time circuit that eliminates the need for external capacitors, reducing component count.
• Offers high-precision voltage detection with configurable thresholds for accurate battery state monitoring.

Applications

• Protection circuits for single-cell lithium-ion battery packs
• Safety management for lithium polymer rechargeable batteries
• Portable electronic devices requiring compact battery protection

Procurement Notes

Verify the specific suffix code to confirm pinout compatibility and detection voltage settings before integration. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the selected variant matches the required package type and thermal specifications for the target application environment.

Selection Notes

Select this component when a compact solution for single-cell Li-ion or Li-Po protection is required. The SOT-25-5 package suits space-constrained designs. Verify that the internal detection thresholds align with the specific battery chemistry requirements without needing extensive external calibration components.

Part Context

This part belongs to the AP9101C series of battery management ICs from Diodes Incorporated. The series focuses on providing robust protection for rechargeable batteries using minimal external components. The AP9101CAK-ACTRG1 variant specifically utilizes the SOT-25-5 package format for surface mount assembly.

Replacement Considerations

Check for other AP9101C variants with different suffixes if alternative detection voltages or package types are needed. Verify functional equivalence with other single-cell protection ICs regarding threshold accuracy and current consumption specifications.
