Description
The ACT2861 is a buck-boost charger with 4 integrated MOSFETs. It offers a high efficiency, low component count, compact solution for 2 to 5 cell battery charging application. It operates from an input voltage range from 4 to 29V. An advanced switch control algorithm allows the buck-boost converter to maintain output voltage regulation with input voltages that are above, below or equal to the output voltage. The ACT2861 is optimized to reduce input current in shipping, shutdown, and standby for applications which are sensitive to quiescent current draw, such as battery-powered devices. The system can be monitored and configured by I²C. The built-in ADC can be read for the information of input/output voltages and currents, and the die temperature. With an MCU, it can easily be configured to charge a multi cell battery pack from a variety of input power sources.
