AP9101CAK6-AATRG1

Overview

The AP9101CAK6-AATRG1 is a single-chip protection IC designed for lithium-ion and lithium-polymer rechargeable battery packs. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge conditions, activating an external MOSFET switch to isolate the battery during faults. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.3 V to 4.275 V. It features low current consumption of 3 µA in operation mode and includes built-in fixed-time circuits to minimize external component requirements. The unit is housed in a surface-mount SOT-26-6 package.

Feature Summary

• Provides comprehensive protection against overcharge, overdischarge, and abnormal current conditions by controlling external MOSFET switches.
• Integrates high-accuracy voltage detection circuits with configurable thresholds for precise battery monitoring.
• Includes built-in fixed-time delay circuits that eliminate the need for external capacitors, simplifying design.
• Operates with ultra-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

Procurement Notes

Verify the specific suffix 'AA' against the manufacturer's official datasheet to confirm exact detection voltage steps and hysteresis values, as these parameters vary across the AP9101C series. Confirm availability status directly with Diodes Incorporated or authorized distributors, as inventory levels fluctuate. Ensure the SOT-26-6 package footprint matches the target PCB layout. Check for RoHS compliance documentation if required for the end product.

Selection Notes

Select this component when designing for single-cell Li-ion or Li-Po batteries requiring integrated protection without complex external timing components. The choice depends on the specific overcharge and overdischarge voltage thresholds needed for the target cell chemistry. Consider the low operating current for applications prioritizing battery life. Verify that the SOT-26-6 package is compatible with the assembly process and available manufacturing capabilities.
