DIODES Incorporated Integrated Circuits (ICs) - Power Management (PMIC) - Battery Management AP9211SA-AG-HAC-7

The AP9211 is a single-chip battery protection solution designed specifically for 1-cell lithium-ion rechargeable battery packs. It integrates a battery protection chip and dual n-channel MOSFETs with a common drain configuration. The device offers comprehensive protection features, including overcharge and overdischarge voltage/current detection, load short circuit protection, and built-in fixed delay time to minimize external component requirements. The AP9211 operates with a high voltage CMOS process, supporting input voltages up to 30V. It features low quiescent current consumption, with typical values of 3.0µA in normal mode and 0.1µA in power-down mode. The device provides high-accuracy voltage detection for various operational parameters, including overcharge and overdischarge thresholds, with specified accuracy levels. The product is packaged in a U-DFN2030-6 (Type C) format, suitable for surface mount applications. It is compliant with RoHS standards and is free from halogens and antimony, making it a "green" device. The AP9211 is not recommended for new designs, and engineers should consider this when evaluating its suitability for their projects.
