FUSB301A  
Autonomous USB Type-C  
Controller with  
Configurable I2C Address  
Description  
www.onsemi.com  
The FUSB301A is a fully autonomous Type-C controller optimized  
for < 15 W applications. The FUSB301A offers CC logic detection for  
Source Mode, Sink Mode, DRP, accessory detection support, and dead  
2
battery support. The FUSB301A features configurable I C address  
toꢀsupport multiple ports per system. The FUSB301A features an  
extremely low power disable mode as well as low power during  
normal operation. It is available in an ultra thin, 12-Lead TMLP  
Package.

Dead Battery  
in a high impedance state by default after powerup or  
device reset, and the global interrupt mask (INT_MASK in  
Control register) is set. After INT_MASK bit is cleared by  
the local processor, the INT_N pin stays high impedance in  
preparation of future interrupts. When an interruptible event  
occurs, INT_N is driven LOW and is in a high impedance  
state again when the processor clears the interrupt by reading  
the interrupt registers. Subsequent to the initial power up or  
reset; if the processor writes a “1” to global interrupt mask  
bit when the system is already powered up, the INT_N pin  
stays in a high impedance state and ignores all interrupts  
until the global interrupt mask bit is cleared. If an event  
happens that would ordinarily cause an interrupt when the  
global interrupt mask bit is set, the INT_N pin goes LOW  
when the global interrupt mask is cleared.  
If power is not applied to FUSB301A and it is attached to  
a Source device, then the Source would pull up the CC line  
connected through the cable. The FUSB301A in response  
would turn on the pulldown that will bring the CC voltage  
to a range that the Source can detect an attach and turn on  
VBUS.  
Power Up, Initialization and Reset, Interrupt Operation  
When power is first applied, the FUSB301A will power  
up in Sink mode with all interrupts masked. The local  
processor must configure the FUSB301A to the desired  
mode and clear the global interrupt mask bit, INT_MASK.  
The INT_N pin is an active low, open drain output. This pin  
indicates to the host processor that an interrupt has occurred  
in the FUSB301A which needs attention. The INT_N pin is
