Description
SC0163D is a low-cost USB high-voltage dedicated charging port (HVDCP) interface IC for the Quick Charge 3.0 specification.  It
incorporates all necessary functions to add Quick Charge 3.0 capability to Power Integrations’ switcher ICs such as InnoSwitch, TinySwitch, TOPSwitch and other solutions employing traditional secondary-side feedback schemes.
SC0163D supports the full output voltage range of Class A per Quick Charge 3.0 specification.
SC0163D automatically detects whether a connected (PD) is Quick
Charge 3.0 or Quick Charge 2.0 capable before enabling output voltage adjustment.  If a PD not compliant to Quick Charge 2.0 or 3.0 is detected the SC0163D disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs.

PRELIMINARY
Functional Description
SC0163D is a low-cost USB high-voltage dedicated charging port (HVDCP) interface IC for the Quick Charge 3.0 specification.  It incorporates all necessary functions to add Quick Charge 3.0
capability to Power Integrations’ switcher ICs such as InnoSwitch, TinySwitch, and TOPSwitch.
SC0163D also supports other solutions with traditional secondary-side feedback schemes such as TL431 for instance.
Figure 5 depicts SC0163D interfacing with Power Integrations’ InnoSwitch switcher IC.
SC0163D supports the full output range of Quick Charge 3.0 Class A (3.6 V to 12 V) and its subset Quick Charge 2.0 Class A (5 V, 9 V, or 12 V).  It automatically detects either Quick Charge 3.0 or Quick Charge 2.0 capable powered devices (PD) or legacy PDs compliant with USB Battery Charging Specification revision 1.2 and only enables output voltage adjustments accordingly.
Shunt Regulator
The internal shunt regulator clamps the BYPASS pin at 6 V when
current is provided through an external resistor (R BP  in Figure 5). This facilitates powering SC0163
D externally over a wide output voltage range of 3.6 V to 20 V.  Recommended values are R BP  = 2.21 k Ω ±1% and C BP  = 470 nF.
BYPASS Pin Undervoltage
The BYPASS pin undervoltage circuitry resets the SC0163D when the BYPASS pin voltage drops below 2.87 V.  Once the BYPASS pin
voltage drops below 2.87 V it must rise back to 3.1 V to commence correct operation.
Reference and Output Voltage Range Selection Input
Resistor R REF  at the REFERENCE pin is connected to an internal band gap reference and provides an accurate reference current for internal timing circuits.  Recommended value is R REF  = 38.3 k Ω ±1%. Quick Charge 3.0 Interface
At power-up SC0163D turns on switch N1 (see Figure 3) short-circuit-ing USB data lines D+ and D- for the initial handshake between
AC-DC adapter (DCP) and powered device (PD) as described in the USB Battery Charging specifica
tion revision 1.2.  After the USB BC 1.2 handshake is completed, SC0163D will turn off switch N1 if it detects a Quick Charge 3.0 or Quick Charge 2.0 compliant PD. At this point the Quick Charge 2.0 handshake followed by the Quick Charge 3.0 handshake can take place as described in the Quick Charge 2.0 and Quick Charge 3.0 protocol specification.  Upon completion of the Quick Charge 2.0 and Quick Charge 3.0 handshakes, SC0163D will turn on switch N2 (see Figure 3) connecting a 19.53 k Ω pull-down resistor to USB data line D-.
Table 1 summarizes the output voltage lookup and model select table and corresponding AC-DC adapter output voltages.
When the USB cable is unplugged the voltage level at D+ is pulled down by SC0163D’s internal resistor (see Figure 3).  Once it drops below 0.325 V SC0163D will enter default mode (switch N1 is on, switch N2 is off) and sets the default output voltage of 5 V.
Feedback Loop Drive
SC0163D sets the respective output power supply voltage regulation point by directly driving the reference input of the power supply
control loop error amplifier through an internal current sink I T(UP) and source I T(DO) (see Figure 6).

PRELIMINARY
In default mode with a 5 V output both, the internal current source and current sink are off.  To meet the output voltage step size requirement of ±0.2 V in Quick Charge 3.0 continuous mode, the mandatory value for the upper resistor in the output sensing voltage divider is R1 = 100.0 k Ω ±1%.  For a FEEDBACK pin reference voltage of 1.265 V for instance used by Power Integrations’ Inno-Switch switcher IC the resulting value for R2 = 34.0 k Ω ±1% to set the default output voltage to 5 V.
