AP9101CAK6-ACTRG1

Overview

The AP9101CAK6-ACTRG1 is a single-chip protection IC designed for lithium-ion and lithium-polymer rechargeable battery packs. Manufactured by Diodes Incorporated, it integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge current conditions. The device controls external MOSFET switches to isolate the battery during fault events. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.5 V to 4.375 V. Packaged in an SOT-25-5 surface-mount format, it functions reliably across temperatures from -40°C to +85°C with a typical operating current of 3 µA.

Feature Summary

• Integrates high-precision voltage detection for monitoring overcharge and overdischarge states
• Provides automatic protection against overcurrent and abnormal battery conditions
• Eliminates need for external timing capacitors via built-in fixed time circuits
• Operates with low power consumption suitable for portable electronic devices

Applications

• Single-cell lithium-ion battery pack protection
• Lithium-polymer battery management systems
• Portable consumer electronics requiring compact battery safeguards
• Mobile communication devices with integrated power management

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm package integrity and marking alignment with official datasheet specifications. Request batch-specific documentation to ensure compliance with RoHS directives and REACH regulations. Validate part number suffixes against current manufacturing revisions to avoid obsolete variants. Maintain proper ESD handling protocols during storage and assembly processes.

Selection Notes

Select this component for applications requiring precise single-cell battery protection without complex external circuitry. Ensure the required detection voltage thresholds align with specific cell chemistry characteristics. Verify that the SOT-25-5 package dimensions fit the target PCB layout constraints. Consider the operating temperature range compatibility with the intended environmental conditions. Evaluate the low standby current benefit for extending battery life in sleep modes.

Part Context

This component belongs to the AP9101C series of battery management ICs from Diodes Incorporated. The series focuses on providing comprehensive protection for single-cell Li-ion and Li-Po batteries in a minimal footprint. It represents a solution for integrating safety features directly into compact power management designs, reducing bill-of-materials complexity compared to discrete protection approaches.

Replacement Considerations

Consult official Diodes Incorporated substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters before considering any third-party equivalents. Ensure any substitute maintains identical detection accuracy and package compatibility.
