General Description

The RTQ2117A combines a charging port controller, USB 2.0 high-speed data line (D+/D-) switch and a 3A synchronous buck converter.

The RTQ2117A provides the electrical signatures on D+/D- to support charging schemes compatible with the USB 2.0 Battery Charging Specification BC1.2 and Chinese Telecommunication Industry Standard YD/T 1591-2009.

Auto-detect mode is also integrated which supports USB 2.0 Battery Charging Specification BC1.2 Dedicated Charging Port (DCP), Divider 3 mode and 1.2V shorted mode to comply with the legacy fast charging mode of mobile devices.

Overview

RTQ2117A-QA Charging Port Controller and Integrated 36V 3A Synchronous Buck Converter.

Key Features

include cycle-by-cycle current limit for protection against shorted outputs, soft-start control to eliminate input current surge during start-up, input under-voltage lockout, output under-voltage protection, output over-voltage protection and over-temperature protection. The RTQ2117A can be used to support Type-A connector. The RTQ2117A is fully specified over the temperature range of TJ =.
40°C to 125°C and available in WETD-VQFN-32L 5x5.
