Description
General part information
TPS25846-Q1 Series
The TPS25846-Q1 is a USB Type-A BC1.2 charging solution that includes a synchronous DC/DC converter. With cable droop compensation, the Vbus voltage remains constant regardless of load current, ensuring connected portable devices are charged at optimal current and voltage even under heavy loads.
The TPS25846-Q1 includes high bandwidth analog switches for DP and DM pass-through. The device also integrates short to battery protection on VBUS, DM_IN and DP_IN pins. These pins can withstand voltage up to 18 V.
The synchronous buck regulator operates with current mode control and is internally compensated to simplify design. A resistor on the RT pin sets the switching frequency between 300 kHz and 2.2 MHz. Operating below 400 kHz results in better system efficiency. Operation above 2.1 MHz avoids the AM radio bands and allows for use of a smaller inductor.
