AP9101CK6-BKTRG1 is a Power Management IC (PMIC) which is designed for battery management applications. This article will delve into the application fields and working principles of AP9101CK6-BKTRG1.

Application Field

AP9101CK6-BKTRG1 is mainly applied to Li-ion/Li-polymer battery management, standby power supply system and load shedding system. It is widely used in portable electronic product such as mobile, digital products, tablet PC, laptop and industrial control fields. The main external components are load and battery.

The typical function of AP9101CK4-BKTRG1 is to control Li-based battery and keep the voltage, current and temperature within a certain range. It can also provide protection from over temperature, over charging, over discharging and short circuit. In addition, AP9101CK6-BKTRG1 ranges provide an adjustable charge current, 200Kbps I2C interface and an ARM Cortex-M0 microcontroller including a Flash memory.

Working Principle

AP9101CK6-BKTRG1 provides three charging modes, i.e Standby Mode, Constant Voltage Mode and Constant Current Mode. When the voltage of battery is lower than 3V, AP9101CK6-BKTRG1 can automatically enter Standby Mode and the device will be powered off. When the voltage of battery is higher than 3V, the device will enter Constant Voltage Mode. The AP9101CK6-BKTRG1 can provide a constant voltage of 4.2V and a constant current from 300mA to 1800mA (adjustable).

The AP9101CK6-BKTRG1 is also capable of monitoring other parameters. It has an adjustable charging temperature range from -40 to 75℃, which can ensure that the output current is safely adjusted according to temperature changes. It also can monitor battery’s current and capacity, providing information you need with high accuracy. Moreover, AP9101CK6-BKTRG1 provides overcharging, over-discharging, over-current and short-circuit protection. It also provides an accurate temperature monitoring system with high accuracy, capable of detecting the external temperature or dissipating temperature.

Conclusion

AP9101CK6-BKTRG1 is a professional PMIC from the AP9101 series which is primarily designed for battery management applications. The device provides three charging modes and adjustable current, voltage and temperature ranges. It also can monitor battery’s current and capacity and provides protective features. AP9101CK6-BKTRG1 is widely used in Li-ion/ Li-polymer battery management and industrial control fields.
