  • The FAN6100HM is a highly integrated secondary side constant voltage and constant current controller that is compatible with MediaTek Pump ExpressTM Plus and Fairchild’s FCP-Single communication protocol specifications. It is designed for use in applications that requires Constant Voltage (CV) and Constant Current (CC) regulations.
    The controller consists of two operational amplifiers for voltage and current loop regulation with adjustable reference voltage. The CC control loop also incorporates a current sense amplifier with gain of 10. Outputs of the CV and CC amplifiers are tied together in open drain configuration.
    The FAN6100HM enables power adaptor’s output voltage adjustment if it detects a protocol capable powered device. It can be capable of outputting 5 V at the beginning, and then 7 V, 9 V or 12 V to meet requirements of a High Voltage Dedicated Charging Port (HVDCP) power supply or 4.8 V, 4.6 V, 4.4 V, 4.2 V or 4 V to maximize the charging current which is controlled by the power adaptor. If a non compliant powered device is detected, the controller disables output voltage adjustment to ensure safe operation with smart phones and tablets that support only 5 V.
    FAN6100HM also incorporates an internal charge pump circuit to maintain CC regulation down to the power supply’s output voltage, Vbus of 2 V without an external voltage supply to the IC. Programmable cable voltage drop compensation allows precise CV regulation at end of USB cable via adjusting one external resistor.Compared to the FAN6100M, the FAN6100HM’s maximum current rating is 3 A which can support higher power system design.
    The device is available in the 20-pin MLP 3 x 4 package.
