Texas Instruments TPS25831-Q1 | Demoboard TPS25831Q1EVM-062

Beschreibung

The TPS2583x-Q1 is a USB Type-C and BC1.2 charging port controller 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.The TPS2583x-Q1 also integrates short-to-battery protection on VBUS, CC1, CC2, DM_IN and DP_IN pins. These pins can withstand voltage up to 18 V.The TPS25830-Q1 includes high bandwidth analog switches for DP and DM pass-through, while the TPS25831-Q1 includes a thermistor input pin and thermal warning flag for user programmable thermal overload protection.
