U E K K X Y Z FUSB251 Type-C CC and SBU Protection IC PRODUCT SUMMARY www.onsemi.com General Description The FUSB251 is an I2C controlled switch with over voltage protection on CC and SBU pins in TypeC interface port. The device has SPST switches on CC1/2 and SBU1/2 which enable automatically with valid VDD so that TypeC/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 WLCSP15, 1.49x2.06x0.574 charging. Another feature in FUSB251 is moisture detection on both CASE 567WV CC and SBU paths with ADC detection. Once moisture is detected, and Interrupt is generated and the corresponding register is updated to notify host. The device has onchip IEC protection with surge MARKING protection on both CC and SBU. Both CC and SBU ports are 24 V DC DIAGRAM tolerant. Package type is WLCSP with 15 ball 3x5 array.
