Description
- NCP4371 is a USB secondary side fast-charging controller, supporting Qualcomm Quick Charge™ 3.0 (QC 3.0) High Voltage Dedicated Charging Port (HVDCP) Class A and Class B specification. NCP4371 allows for selection of the output voltage of an AC-DC USB adapter based on commands from the Portable Device (PD) being powered. Selecting a higher charging voltage will reduce the charging current for a given power level resulting in reduced IR drops and increased system efficiency. Another advantage of QC3.0 is a decreased battery charging time and a reduced PD system cost thanks to the ability to select an optimum charging voltage. This eliminates the need for costly DC-DC converters within the PD. The USB-bus voltage can be controlled in discreet steps from 3.6V up to 20V. The output current is limited not to exceed maximum allowable power level. The NCP4371 resides at the secondary (isolated) side of the adapter. It includes voltage and current feedback regulation eliminating the need for a shunt regulator such as TL431. The NCP4371 provides charging current limits down to VBUS=2.2V protecting the portable device from excessive currents in case of a soft short-circuit condition. The NCP4371 integrates a safe-discharge circuitry to quickly and reliably discharge output capacitors in case the USB cable is unplugged or connected to a 5V only USB port.
