  • The FAN54110 is a USB-compatible single-cell, linear Li-Ion charger with support for Dead Battery Provision (DBP). The maximum charge current is rated at 1 A and can be programmed from 100 mA to 1 A through the I2C interface, optimizing charging for various battery sizes. Dynamic Input Voltage Control ensures weak power sources can be used to power the FAN54110 without collapsing to an unusable input voltage for charging. Open-drain status pins, STAT and POK_B, provide a status of charging and input power. The STAT pin also notifies the system processor when an I2C interrupt occurs so the processor can take action based on the interrupt. The FAN54110 conforms to the constraints of the Dead Battery Provision within the BC1.2 specification, including a 30-minute timer that cannot exceed 45 minutes. The FAN54110 is available in a 15- bump, 0.4 mm pitch, WLCSP package.
