DIODES Incorporated Integrated Circuits (ICs) - Power Management (PMIC) - Battery Management AP9221SA-CC-HAC-7

The AP9221SA-CC-HAC-7 is a single-chip battery protection solution designed for 1-cell lithium-ion rechargeable battery packs. It integrates a protection chip and dual N-channel MOSFETs, enabling it to detect and respond to overcharge, overdischarge, and short circuit conditions. The device operates with a high voltage CMOS process, supporting input voltages up to 24V, and features low quiescent current consumption, making it suitable for battery management applications. Key specifications include adjustable overcharge detection voltage ranging from 3.5V to 4.5V, overdischarge detection voltage from 2.0V to 3.4V, and various detection thresholds for overcurrent and short circuit conditions. The AP9221 also includes built-in fixed delay times to minimize external component requirements. It is packaged in a U-DFN2030-6 (Type C) format, which is compact and suitable for space-constrained designs. The product is fully RoHS compliant and is noted for its environmental friendliness, being halogen- and antimony-free. Engineers considering this product should evaluate its specifications against their project requirements, particularly in applications involving single-cell lithium-ion battery management.
