AP9101CK6-CMTRG1

Battery Management Overview

The AP9101CK6-CMTRG1 is a single-cell battery protection IC from Diodes Incorporated, designed for lithium-ion and lithium-polymer rechargeable batteries. It integrates high-precision voltage detection circuits to monitor overcharge, overdischarge, overcharge current, and overdischarge conditions, automatically controlling external MOSFET switches 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 between 2.5 V and 4.275 V. It features low power consumption with a typical operating current of 3 µA at +25°C and a power-down mode current of 0.01 µA. The component is housed in an SOT-26-6 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Battery Management Procurement Notes

Verify the specific suffix 'CM' against the manufacturer's official datasheet to confirm exact detection voltage thresholds and hysteresis values, as these parameters vary significantly across the AP9101C series. Confirm RoHS compliance status and ensure the SOT-26 package matches your PCB footprint requirements before finalizing procurement.

Battery Management Selection Notes

Select this component when designing for single-cell Li-ion or Li-Po applications requiring integrated protection without external timing components. Ensure the required overcharge and overdischarge detection thresholds align with the specific 'CM' variant specifications. Verify that the external MOSFETs selected are compatible with the IC's drive capabilities and that the system operates within the specified voltage and temperature ranges.

Battery Management Part Context

This part belongs to the AP9101C family of battery management ICs from Diodes Incorporated. The family provides a complete solution for protecting single-cell lithium-based batteries by detecting various fault conditions. The AP9101C series is characterized by its ability to minimize external component count through internal timing circuits and offers multiple package options including SOT-25 and SOT-26 for space-constrained designs.

Battery Management Replacement Considerations

Check for other AP9101C variants with different suffixes (e.g., CA, CB, CC) if the detection voltage thresholds of the CM variant do not match the application requirements. Ensure any substitute maintains the same SOT-26 package and functional compatibility with existing external MOSFETs.
