CW6302/CW6304 150/300mA Linear Charger with Power Path

CW6302/CW6304 are high accuracy linear charger ICs with power-path management for wearable devices using Li+ batteries. The minimum charging termination current is 1mA. The power-path management provides dynamic charging control to allow system to drain the maximum load from DC Input, meanwhile charging the battery. They also support system Instant-on even with depleted battery.
