It is designed for use in various applications ranging from cellular, computing, peripherals and automotive system solutions. It is capable of providing a regulated output voltage for charging a variety of battery chemistries, including Nickel-metal Hydride (NiMH), Lithium Polymer (Li-P), Ultralife, and so on. The AP9101CAK-AETRG1 also has a number of safety features, such as overcurrent and overtemperature protection, and undervoltage lockout for NiMH batteries, making it suitable for use in potentially hazardous environments.

Design and Features

The internal design of the AP9101CAK-AETRG1 consists of two main parts- a “charger” and a “management” section. The charger section is responsible for regulating the charging current and voltage. It consists of a power MOSFET switch along with driver and control circuitry. By adjusting the settings of the switch, the charger is able to adjust the current and voltage output to provide the proper charging conditions for the connected battery.

The management section consists of a comparator and logic circuitry. This component continuously monitors the battery voltage and temperature and uses this information to determine when to turn off the charger, when to begin charging again, and when to enable or disable various other features. The available settings are adjustable using programming pins, allowing the user to choose from a range of settings. For example, it is possible to enable undervoltage lockout, Trickle charge mode, or charge/discharge enable settings.

Applications and Benefits
