APPLICATION INFORMATION

Function Description

The UTC UCHQ200 is a USB Dedicated Charging Port Controller can fast charge most of the handheld devices.

It can be like the original charging adapter. The UCHQ200 can support BC1.2, Apple Divider mode, Samsung

device.

The UTC UCHQ200 is a low cost USB high voltage dedicated charging port interface IC for Quick Charge 2.0

specification. It also supports full output voltage range of Quick Charge 2.0 Class A or Class B.

Quick Charge 2.0 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 0.325V and keep 1.25 seconds UCHQ200 into Quick Charge 2.0 operation mode.

The output voltage (12V) can be inhibited by connect VSEN2 to VDD. The output voltage (20V) can be inhibited by

connect VSEN3 to VDD.

If PD without QC 2.0 the device will keep output voltage level 5V guarantee safe operation for only 5V USB PD.

Shunt Regulator

The wide power supply output voltage through external resistor from RVDD to VIN. The internal with Zener-Diode

clamp VIN pin at 6.4V. RVDD=2.2KΩ and CVDD=1uF. RREF=127 KΩ.
