FUSB251 - Type-C CC and SBU Protection IC

General Description

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.

Key Features

  • Low Ron SPST Switches on both CC1/2 and SBU1/2 Path for Type-C.
  • Dead Battery Mode Provides Default Rd Presenting on CC1/2.
  • 24 V DC Tolerant on CC and SBU.
  • ±35 V Surge Protection on CC and SBU.
  • Over Voltage Protection on CC and SBU.
  • I2C Interface with Processor with Interrupt for event Notification.
  • Moisture Detection on CC and SBU Pins.
  • On-chip IEC ESD Protection with External Capacitor on CAP Pin.
  • CC Ron 0.3 W Typ.

Type-C CC and SBU Protection IC FUSB251 PRODUCT SUMMARY General 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 moisture is detected, and Interrupt is generated and the corresponding register is updated to notify host. The device has on-chip IEC protection with surge protection on both CC and SBU.
