JW3702
The JW3702 is a synchronous 4-switch buck-boost controller capable of charging 1-4 cell Li-ion batteries with high light load efficiency and fast transient response. It can charge the battery from a wide range of input sources, such as USB adapter, high voltage USB PD sources and traditional adapters.
The JW3702 supports I2C serial communication interface to program a lot of parameters of the chip, offering a flexible solution for battery charging applications. An internal 10-bit ADC is provided to monitor the bus voltage, bus current, battery voltage, battery current and NTC resistor voltage, so user can monitor the system status in real time.
The device also supports OTG function to deliver power from battery to other portable devices through USB port. And the OTG voltage and current limit can be programmed by I2C interface.
The JW3702 guarantees robustness with battery/ OTG over-voltage protection, bus/ battery under-voltage protection, OTG/ battery over-current protection, charging timeout, watchdog and thermal shutdown.
The JW3702 is available in QFN4X4-32 package.
