描述 Description

The FUSB251 is an I2C controlled over voltage protection switch on CC and SBU pins in Type−C™ interface port. The device has SPST switches on CC1/2 and SBU1/2 which are enabled automatically with valid VDD so that Type−C™ PD controller can use the over voltage protected CC path. The FUSB251 has dead battery mode and CC pulled down with Rd so the source device can provide Vbus for battery charging. Another feature of the FUSB251 is moisture detection on both the CC and SBU paths with ADC detection. Once moisture is detected an interrupt is generated and corresponding the register is updated to notify the host. The device has on−chip IEC protection with surge protection on both CC and SBU paths.Both CC and SBU ports are 20 V DC tolerant.
