Controller

FUSB3307

FUSB3307 is a highly integrated USB Power Delivery (PD) power

source controller that can control a DC−DC port power regulator or the

opto−coupler in the secondary side of an AC−DC adapter. It

implements the Source finite state machines of USB Power Delivery

3.0 (PD 3.0) and Type−C

™ which includes Programmable Power

Supplies (PPS). In order to meet the PPS specification, FUSB3307

supports minimum 3.3 V and maximum 21 V output voltage control.

It includes Constant Voltage (CV) and Constant Current Limit (CL)

control blocks. The references are supported from internal D/A

converters.

FUSB3307 supports various protections, Under Voltage Protection

(UVP), Over Voltage Protection(OVP), Over Current Protection

(OCP), CC1 and CC2 Over Voltage Protection (CC_OVP), VCONN

Over Current Protection (VCONN_OCP), and internal and external

Over Temperature protection (I_OTP and E_OTP). With a 10−bit A/D

converter, output voltage, output current, IC internal temperature and

external temperature via an NTC resistor can be monitored.

FUSB3307 is capable of controlling a single or back−to−back

N−Channel MOSFETs as a load switch, which results in a lower cost

and easier design.
