The ACT82120 provides a complete one cell charging ecosystem optimized for portable electronic devices in a single highly integrated PMIC. This IC combines a 1.5A JEITA switching battery charger with integrated VBAT control MOSFET plus two low IQ LDOs, push-button input, and four 25 mA LED drivers. 

Design flexibility is offered through full programmability of the charging profile including pre-charge current, fast charge current, termination current, charge voltage, and battery temperature protection. Additionally, On-the-Fly adjustments to the charging profile allow for fine-tuned, multi-loop charge profiles through communication with an external MCU or processor. Support for both wireless charging and wired charging over USB-C, with smart selection between options, enhances the flexibility of the PMIC to accommodate the needs of many applications. 

A combination of push-button input and quad channel LED drivers allows for basic end user interaction without the need for microcontroller communication. Onboard NVM storage of all programable settings lets the system be fully operational upon start up with minimal external communication. Communication through the I2C bus allows for configuration of the PMIC during the design process and on-the-fly communication to a microcontroller in end applications.  A small form factor WLCSP and few required external components keep the overall solution size compact.
