Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX77976EFD is a high-performance, high-input 3.5/5.5A fast charger with an integrated Smart Power SelectorTM.The IC acts as a reverse boost without the need for an additional inductor, allowing the battery to share its power supply through the charging port with a voltage adjustable from 5V to 12V. Low-loss power switches are integrated within the device, ensuring high efficiency and small solution size even at high voltage inputs and high charging currents. The device's high switching frequency allows the use of smaller sized external inductors. the IC provides load true disconnect in reverse boost mode and has adjustable output current limit protection.
