TPS2583x-Q1 is a highly-integrated USB Type-C and BC1.2 charging port controller that includes a synchronous DC/DC converter. It also supports DP_IN/DM_IN/CC1/CC2 short-to-battery protect. During the assembly, manufacturing, and maintenance of a car, there is a common problem where the USB port randomly shorts to the car battery, causing chip damage, or the USB lightning port accidentally hits the cigarette lighter during the daily application, which also causes chip damage. The TPS25830, TPS25831-Q1, and TPS25840-Q1 provide DP_IN/DM_IN/CC1/ CC2 short-to-battery protection, and supports 18-V maximum protection voltage, thus avoiding chip damage. All the following tests are based on the TPS25830Q1EVM-040. A power supply plus an external 30-mF electrolytic capacitor was used to simulate the car battery. The test input voltage was 14.5 V, R3 external. The recommended value for External FET is 10R/0603. The recommended value for External FET without External R3 is 100R/0805.
