DESCRIPTION

The UTC UCHQ200 is a fast charge protocol controller and

follows Quick Charge 2.0 specification for smart power bank

application. The protocol feature monitors USB D+/D- data line

voltage, and automatically adjusts output voltage of power bank

and wall adaptor to optimize charge time.

UTC UCHQ200 is a high performance solution for fast-charging

mechanism and it saves charging time. It supports the full output

voltage range of either Class A or Class B. Optionally Class B can

be inhibited for protecting the battery charger from accidental

damage.

UTC UCHQ200 can support not only USB BC compliant

devices, but also Apple / Samsung devices and automatically

detects whether a connected powered device (PD) is Quick

Charge 2.0 capable before enabling output voltage adjustment. If a

PD not compliant to Quick Charge 2.0 is detected the UCHQ200

disables output voltage adjustment to ensure safe operation with
