MAX77757 3.15 A USB Type-C® Autonomous Charger with JEITA

Maxim's charger is designed for 1-cell Li-Ion/LiFePO4 batteries and applications such as power banks

Image of Maxim's MAX77757 3.15A USB Type-C Autonomous Charger with JEITA (click to enlarge)Maxim's MAX77757 is a standalone 3.15 A charger with integrated USB Type-C CC detection with JEITA compliance that supports reverse boost capability. The fast-charge current is easily configured with resistors. The MAX77757 operates with an input voltage of 4.5 V to 13.7 V and has a maximum input current limit of 3 A. The IC implements the 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.

  • Protection: up to 16 V
  • Input operating voltage: 13.7 V (max.)
  • Charging current: 3.15 A (max.)
  • Discharge current protection: 6 A
  • Reverse boost capability: up to 5.1 V, 1.5 A
Applications
  • Mobile point-of-sale (mPOS) terminals
  • Portable medical devices
  • Wireless headphones
  • GPS trackers
  • Charging cradles for wearable devices
  • Power banks
  • Mobile routers
