AP9211SA-DD-HAC-7 is a high performance power management integrated circuit (PMIC) designed with the Battery Management System (BMS). It is designed to manage the charging of batteries and provide protection from over and under current, over temperature and short circuit conditions. The AP9211SA-DD-HAC-7 is suitable for applications such as automotive and industrial.

The AP9211SA-DD-HAC-7 offers a comprehensive set of features for managing and protecting rechargeable Li-ion and LiPo batteries. It features two step charging and two step discharging, a charge current and discharge current limit setting, and a cell temperature monitor. It also has a low sleep current and a low-voltage lockout feature to prevent the over discharge of the battery. The AP9211SA-DD-HAC-7 also features an auto-switching feature to maximize battery utilization. In addition, it provides a charging status indication output and an indication of when the battery is full.

The AP9211SA-DD-HAC-7 operates with up to five Li-ion or LiPo cells in series. It provides a regulated output voltage of 5V with a wide range of charge currents from 0.1A to 4A. The discharge current is adjustable from 0.1A to 10A. The voltage range of the cells can be set from 2.7V to 4.2V with a resolution of 0.02V. The AP9211SA-DD-HAC-7 also has an integrated low RDS(on) MOSFET switch for charging and discharging control.

The AP9211SA-DD-HAC-7 has an on-chip battery temperature monitoring system. The temperature range can be set from -20°C to 70°C with a resolution of 0.1°C. It features an adjustable over temperature protection limit, a hysteresis temperature setting, and a separate temperature detection output for external monitoring.

In addition, the AP9211SA-DD-HAC-7 has a charge cycle timer with adjustable pre-charge, equalization and termination times. It also has separate enable pins for charge and discharge current enable. The charge current sensing is through an external sense resistor, while the discharge current sense is through an integrated current sense amplifier.

The AP9211SA-DD-HAC-7 is an excellent choice for automotive or industrial applications that require a high performance battery management solution. Its features allow it to effectively manage and protect Li-ion or LiPo batteries and ensure a long battery life.
