FUSB251 Product details

Description

The FUSB251 is an I2C controlled switch with over voltage protection on CC and SBU pins in Type-C interface port.The device has SPST switches on CC1/2 and SBU1/2 which enable automatically with valid VDD so that Type-C/PD controller can use the over voltage protected CC path.The FUSB251 has dead battery mode, CC pulled down with Rd, where Source device can provide Vbus for battery charging.Another feature in FUSB251 is moisture detection on both CC and SBU paths with ADC detection.Once moist
