AP9101CK6-CGTRG1

Battery Management Overview

The AP9101CK6-CGTRG1 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 2.5 V to 4.275 V. The device features a typical operating current of 3 µA at +25°C with a 3.5 V supply, and a power dissipation rating of 250 mW. It provides overcharge and overcurrent fault protection for 1-cell battery packs. The component is housed in an SOT-26 (SOT-23-6) surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Battery Management Feature Summary

• Integrates high-precision voltage detection circuits to monitor overcharge and overdischarge conditions without requiring external capacitors for timing.
• Controls external MOSFET switches to isolate the battery during abnormal states such as overcurrent or overvoltage events.
• Designed for low-power operation with minimal quiescent current consumption in active mode.

Battery Management Applications

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

Battery Management Procurement Notes

Verify the specific suffix CG against the official Diodes Incorporated datasheet to confirm exact electrical tolerances and pinout configurations. Confirm RoHS compliance status and REACH registration details prior to integration. Check for any product change notifications or end-of-life announcements that may affect long-term availability. Ensure the SOT-26 footprint matches the target PCB design guidelines.

Battery Management Selection Notes

Select this component for applications requiring a compact, single-cell battery protection solution with built-in timing circuits. Compare the 3 µA operating current against system standby requirements. Verify that the SOT-26 package size fits the mechanical constraints. Ensure the external MOSFET selection aligns with the IC's drive capabilities and the expected load currents.
