MAX77860 Datasheet | Maxim Integrated

Description The MAX77860 is a high-performance single input switch mode charger that features USB Type-C CC detection capability in addition to reverse boost capability and a Safeout LDO. This switched-mode battery charger with two integrated switches, provides small inductor and capacitor sizes, programmable battery charging current, and is ideally suited for portable devices such as smartphones, Io T devices, and other Li-ion battery powered electronics. The charger features a single input, which works for both USB and high voltage adapters. It supports USB Type-C CC detection under BC 1.2 specification, and the power-path switch is integrated in the chip. All MAX77860 blocks connected to the adapter/USB pin are protected from input overvoltage events up to 14V. The USB-OTG output provides trueload disconnect and is protected by an adjustable output current limit. It has an input current limit up to 4.0A and can charge a single-cell battery up to 3.15A. When configured in reverse-boost mode, the IC requires no additional inductors to power USB-OTG accessories. The switching charger is designed with a special CC, CV, and die temperature regulation algorithm, as well as I2C programmable settings to acmodate a wide range of battery sizes and system loads. The on-chip ADC can help monitor the charging input voltage/current, battery voltage, charging/ discharging current, and the battery temperature. The MAX77860 municates through an I2C 3.0 patible serial interface consisting of a bidirectional serial data line (SDA) and a serial clock line (SCL). The IC is available in a 3.9mm x 4.0mm, 81-bump (9 x 9 array), 0.4mm pitch, wafer-level package (WLP).
