charging port interface IC for Qualcomm® Quick ChargeTM 2.0/3.0 class A , HiSilicon FCP specification. The is a USB Ded icated Charging Port Controller can fast charge most of the handheld devices. It can be like the original charging adapter. can support BC1.2, Apple, Samsung and HUAWEI. It also supports full output voltage range of QC 3.0 Class A(3.6V to 12V) or QC 2.0 Class A(5V,9V,12V) SFT430C enter continuous mode. Each 0.325V and keep 1.25 seconds SFT430C Quick Charge 2.0/3.0 Interface Power up D+/D- is supply 2.7V to Apple Device and then supply D+ short to D - into BC1.2. Set the output voltage level 5V. If D+ continuous above can automatic choose into Quick Charge 2.0 /3.0, FCP operation mode. When VDAT(REF)< D+ <V SEL_REF and D- > VSEL_REF , the step D+ from 1V to 3V Pulse-width during 200us cause current sink 2uA by FBO. The maximum output sink current is 70uA for output voltage reach to 12V. Each step D - from 3V to 1V Pulse -width during 200us cause current source 2uA by FBO. The minimum output source current is 14uA for output voltage reach to 3.6V. If PD without QC 2.0 the device will keep output voltage level 5V guarantee safe operation for only 5V USB PD. When USB cable unplug the D+ voltage < V DA T(REF) and output voltage recovery default mode 5V. SFT430C already access QC2.0/3.0 or FCP fore SFT430C start detection. When Shunt Regulator The wide power supply output voltage through external resistor from R VDD to VDD. The inte rnal with Zener -Diode clamp VDD pin at 6.4V. Recommend RVDD =2.2kΩ and CVDD=470nF. QC_EN Function When QC_EN pin disable QC 2.0/3.0,FCP function by connect to GND. Otherwise, enable function by connect to VDD or floating. QC_EN signal need to mode, the mode won’t be changed by setting QC_EN pin signal (High to Low). be ready be SFT430C-Preliminary 0.1-Oct-2016 www.shouding.net
