MAX77757 Image

The MAX77757 from Maxim Integrated is a USB Type-C Autonomous Charger with for 1-Cell Li-ion/LiFePO4 Batteries. It has an input voltage of 4.5 to 13.7 V and has an input current of up to 3 A. This JEITA-compliant charger supports termination voltage of 4.1 to 4.5 V for Li-ion and Li-poly batteries, and 3.6 to 3.7 V for LiFePO4 batteries. It offers reverse-boost capability up to 5.1 V and provides discharge current protection of up to 6 A. This charger is equipped with a smart power selector and a battery true-disconnect FET to control the charging and discharging of the battery or to isolate the battery in case of a fault condition. It can be controlled via a USB interface and has an adaptive input current limit (AICL) function that regulates the input voltage by reducing input current to prevent the voltage of a weak adapter from collapsing or folding back.

The MAX77757 is available in a surface-mount package that measures 3 x 3 mm and is ideal for mobile point-of-sale (mPOS) terminals, portable medical devices, wireless headphones, GPS trackers, and charging cradles for wearable devices, power banks, and mobile routers applications.
