AP9101CK-AZTRG1

Battery Management Overview

The AP9101CK-AZTRG1 is a single-chip protection IC designed for one-cell lithium-ion or lithium-polymer rechargeable batteries. Manufactured by Diodes Incorporated, it integrates high-precision voltage detection circuits to safeguard against overcharge, overdischarge, and abnormal current conditions by controlling external MOSFET switches. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports output voltages from 2.8 V to 4.4 V. It features low power consumption with typical operation current of 3.0 µA at 3.5 V and ultra-low standby current of 0.01 µA in power-down mode. Packaged in an SOT-25-5 surface-mount format, it functions reliably across temperatures from -40°C to +85°C.

Battery Management Procurement Notes

Verify the specific suffix AZ against the official Diodes Incorporated datasheet to confirm exact detection voltage thresholds and hysteresis values. Ensure the SOT-25-5 package matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Battery Management Selection Notes

Select this component when designing protection for single-cell Li-ion or Li-Po batteries requiring minimal external components. The integrated timing circuit reduces bill of materials cost. Verify that the required overcharge and overdischarge detection voltages align with the available options in the AP9101C series. Ensure the operating temperature range meets your application environment constraints.

Battery Management Part Context

This part belongs to the AP9101C series of battery management ICs from Diodes Incorporated. The series offers various detection voltage configurations to suit different battery chemistries and cell counts. The AP9101CK variant specifically denotes the SOT-25 package option, distinguishing it from the SOT-26 versions available in the same family.

Battery Management Replacement Considerations

Check for other AP9101C variants with matching detection voltages if the AZ suffix is unavailable. Cross-reference pinouts between SOT-25 and SOT-26 packages if considering alternative package types within the same series.
