ON SEMICONDUCTOR NCP4371AACDR2G Special Function IC, USB Dedicated Charging Port Controller & Power Switch, 2.2V to 28V in, SOIC-8 New
The NCP4371AACDR2G is a Qualcomm quick charge 3.0 HVDCP controller in 8 pin SOIC package. It 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. The NCP4371 allows for selection of output voltage of an AC to DC USB adapter based on commands from the portable device (PD) being powered. Selecting a higher charging voltage will reduce 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 ability to select an optimum charging voltage. This eliminates need for costly DC to DC converters within 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 secondary (isolated) side of adapter.
Wide operating input voltage range from 2.2V to 28V and low supply current of 300µA
Output voltage configured in discreet steps from class A (3.6V up to 12V), class B (3.6V up to 20V)
Compatible with USB battery charging specification revision 1.2 (USB BC1.2)
Constant voltage and constant current regulation
Soft short circuit current limitation down to VBUS = 2.2V
Removes a need for secondary side shunt regulator such as TL431
Output capacitor safe discharge circuitry at cable unplug
Fast dynamic response and built-in power limiting function
Operating temperature range from -40°C to 125°C
Provides charging current limits down to VBUS = 2.2V
