The MAX77757 is a standalone 3.15A 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 4.5V to 13.7V and has a maximum input current limit of 3A. The IC also 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.The USB Type-C Configuration Channel (CC) detection pins on the MAX77757 enable automatic USB Type-C power source detection and input current limit configuration. To support a variety of legacy USB types as well as proprietary adapters, the IC also integrates BC1.2 detection using the D+ and D- pins. The IC runs the CC pin and BC1.2 detection automatically as soon as a USB plug is inserted without any software control.The IC also offers reverse-boost capability up to 5.1V and 1.5A, which can be enabled with the ENBST pin. The STAT pin indicates charging status while the INOKB pin indicates valid input voltage. Charging can be stopped by pulling the THM pin low.The MAX77757 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. The MAX77757 is offered in several variants to support Li-ion batteries with various termination voltages from 4.1V to 4.5V. It also has a 3.6V termination voltage option for LiFePO4 batteries. The IC comes in a 3mm x 3mm, 0.4mm pitch, 24-lead FC2QFN package making it suitable for low-cost PCB assembly.ApplicationsMobile Point-of-Sale (mPOS) TerminalsPortable Medical DevicesWireless HeadphonesGPS TrackersCharging Cradles for Wearable DevicesPower BanksMobile Routers
