onsemi's FUSB3307 is a highly-integrated USB power delivery (PD) power source controller that offers exceptional features for various applications, including wall chargers for tablet PCs and laptop batteries. This device implements the source finite state machines of USB PD3.0 and Type-C, including programmable power supplies (PPS), ensuring compatibility and adherence to industry standards.
The FUSB3307 supports a minimum of 3.3 V and a maximum of 21 V output voltage control, providing flexibility for different applications. It includes constant voltage (CV) and constant current limit (CL) control blocks, supported by internal D/A converters, enabling precise power delivery control.
To ensure safe and reliable operation, the FUSB3307 includes various protections, including undervoltage protection (UVP), overvoltage protection (OVP), overcurrent protection (OCP), CC1 and CC2 overvoltage protection (CC_OVP), VCONN overcurrent protection (VCONN_OCP), and internal and external overtemperature protection (I_TOP and E_OTP).
With a 10-bit A/D converter, the FUSB3307 can monitor output voltage, output current, IC internal temperature, and external temperature via an NTC resistor, providing accurate feedback to control power delivery.
The FUSB3307 can control a single or back-to-back N-channel MOSFETs as a load switch, resulting in a low cost and easier design. This feature enables designers to save valuable board space and reduce the overall cost of the system.
In summary, onsemi's FUSB3307 highly-integrated USB power delivery controller offers exceptional features for various applications, including wall chargers for tablet PCs and laptop batteries. With its comprehensive protections, precise power delivery control, and easy-to-use load switch control, the FUSB3307 provides a reliable and efficient solution for power source applications.
