PRODUCTION DATA
CCx protection consists of IEC ESD and overvoltage protection.
The CC pins integrate an IEC ESD cell to provide ESD protection up to ±1- kV air discharge and ±8-kV contact discharge per IEC 61000-4-2 (See the ESD Ratings section for test conditions). An additional 0.22-uF capacitor placed close to the CC pin is recommended in real application.
Overvoltage protection (OVP) is provided for short-to-VBUS or short-to-battery conditions in the vehicle harness. When the voltage on CC1 or CC2 exceeds 6.1 V (typical), the TPS2583x-Q1 device immediately shut off CC line. FAULT signal will assert after 8-ms deglitch time. See Figure 11-33.
For CC1 and CC2, when OVP is triggered, the device turns on an internal discharge path with 55-kΩ resistance to ground. On removal of the overvoltage condition, the pin automatically turns off this discharge path and returns to normal operation.
