MAX77860 USB Type-C, 3A Switch-Mode Buck Charger with Integrated CC Detection, Reverse Boost, and ADC General Description Benefits and Features The MAX77860 is a high-performance single input switch Single-Cell Switch Mode Charger mode charger that features USB Type-C CC detection ca- Up to 14V Protection pability in addition to reverse boost capability and a Safe- 4.0V to 13.5V Input Operating Range out LDO. Switching Charger with D+/D- Charger Detection Up to 4.0A Input Current Limit with Adaptive Input This switched-mode battery charger with two integrated Current Limit (AICL) switches, provides small inductor and capacitor sizes, pro- Up to 3.15A Battery Charging Current Limit grammable battery charging current, and is ideally suited Optional External Sense Resistor for portable devices such as smartphones, IoT devices, CC, CV, and Die Temperature Control and other Li-ion battery powered electronics. The charger Supports USB-OTG Reverse Boost, up to 1.5A features a single input, which works for both USB and high Current Limit voltage adapters. It supports USB Type-C CC detection Master-Slave Charging Capability, up to 6A Charge under BC 1.2 specification, and the power-path switch is Current integrated in the chip. All MAX77860 blocks connected to Integrated Battery True-Disconnect FET the adapter/USB pin are protected from input overvoltage Rated up to 9A , Discharge Current Limit RMS events up to 14V. The USB-OTG output provides true- (Programmable) load disconnect and is protected by an adjustable output current limit. It has an input current limit up to 4.0A and USB Type-C Detection can charge a single-cell battery up to 3.15A.
