AP9101CAK-AJTRG1

Overview

The AP9101CAK-AJTRG1 is a single-cell lithium-ion or lithium polymer battery protection IC manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.4 V to 4.5 V. The device features a typical operating current of 3 µA and a power dissipation rating of 250 mW. It functions across an ambient temperature range of -40°C to +85°C. The component is housed in an SOT-25-5 surface-mount package.

Feature Summary

• Provides comprehensive battery protection by detecting overcharge, overdischarge, overcharge current, and overdischarge current conditions.
• Integrates a fixed-time circuit that eliminates the need for external capacitors, reducing the requirement for external components.
• Utilizes a high-precision voltage detection circuit to monitor battery status with specified accuracy thresholds.

Applications

• Protection circuits for single-cell lithium-ion rechargeable battery packs
• Safety management for lithium-polymer battery systems
• Portable electronic devices requiring low-power battery monitoring

Procurement Notes

Verify the specific suffix AJ against official Diodes Incorporated documentation to confirm exact detection voltage steps and hysteresis values. Confirm RoHS compliance status through the manufacturer's latest environmental statement. Ensure the SOT-25-5 package dimensions match the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing protection for single-cell Li-ion or Li-Po batteries requiring minimal external parts. The integrated timing circuit simplifies design complexity compared to solutions requiring external capacitors. Ensure the application voltage stays within the 1.5 V to 5.5 V operational range and consider the 3 µA quiescent current for low-power standby applications.
