Qualcomm Quick Charget
3.0 HVDCP Controller
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 3.6 V up to 20 V. 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 = 2.2 V 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 5 V only USB port.

APPLICATION INFORMATION
The NCP4371 is designed to operate as an output voltage
the unplug event is detected the decoder circuitry turns−on
an internal current sink, which discharges the output
capacitors to a safe voltage level. If the NCP4371 is set to a
Continuous mode it responds to the PD requests in a Single
request mode. It does not support Group request mode.
and current controller for USB chargers, which resides on
the secondary side of the off−line adapter. It enables to
accommodate the output voltage based on the request from
the portable device in order to optimize the battery charge
time. The NCP4371 is compatible with Qualcomm Quick
Charge 3.0 HVDCP specification. The output voltage can be
increased or decreased in discrete steps. The output current
is limited not to exceed the maximum power limit for given
output voltage level. The internal discharge switch
discharges the output capacitors to a safe voltage level in a
case of the cable unplug.

Power Limit
Once the Power limit is defined by an R_SENSE selection
the user needs to define a maximum output current limit.
This current limit can be given by a connector or cable
maximum current rating.
The protocol decoder and the power limit logic will limit
maximum output current to keep regulation within
recommended V /I operating range. The Power Limit
out out
block adjusts V
voltage reference at the current
There are 5 current limit options available for Power
Option A and 8 current limit options for Power Option B and
C. Each power limit option corresponds to a particular
REFC
regulation loop in order to limit the maximum output current.
The NCP4371 is designed to give a user a high degree of
freedom to optimize maximum power and current limit
profile of the target application. The user can scale both –
maximum output power and maximum current limit
independently.
The NCP4371 has two constant power curves defined –
“Option A” for Class A only and “Option B” for either Class
A or Class B. Power Option C shall be used for applications
where constant power regulation is not required. If Power
Option C is selected then power limiting curve is ignored.
The applications based on Power Option C operate in
“constant current regulation mode”.
Current Control Reference Voltage (V
), which limits
REFC
the maximum output current for the selected R_SENSE
resistor. The user has to make a selection from current limit
characteristics shown in Figure 24. Each power limit curve
represents a unique device option (see Table Device
Options).

In order to scale the power limit curve for the given power
a selection of the current sense resistor has to be done. The
relation between current sense resistor and output power

Soft Short−Circuit Protection
Discharge
In case of a short−circuit at the USB cable end or the
portable device USB receptacle it is desired to limit the short
circuit current to prevent a portable device or cable from a
damage. The NCP4371 offers an extended region of output
If voltage level lower than actual V

the discharge circuitry discharges the output capacitors to
reach the new voltage level in a short time. As well, the
discharge circuitry is activated if cable unplug event is
detected. The NCP4371 features two discharge paths. By
default, the discharge is done via built−in regulated current
source at VCC pin. If the VCC pin discharge capability is not
sufficient an external discharge resistor R
