New USB-C 1.3 Devices For Smartphones, Laptops And Cars


As USB-C adoption keeps growing across the industry, ON Semiconductor is enabling easy integration into USB-C systems with its latest USB-C (Type-C) devices — including two controllers and a switch — fully compliant with the latest revision 1.3 specifications. They are aimed at applications such as smartphones, tablets, and laptops, as well as industrial and automotive use cases.

The FUSB303 port controller can convert existing and new systems to USB-C interface, supporting applications requiring Source (SRC), Sink (SNK), or Dual Role Port (DRP) modes. The new device provides autonomous detection and requires minimal processor interaction and firmware support, providing flexibility and offering customization options.

The company claims that the FUSB303 is power-efficient for mobile and ultra-portable applications, claiming a standby mode consumption of fewer than 10 microamperes (μA). In addition, an ultra-thin (1.6 x 1.6 x 0.375mm) QFN-12 package is thinner than standard CSP packaging, allowing use in increasingly space-constrained designs.


Another device added to the portfolio is the FSUSB242, a USB-C compliant Port Protection Switch that provides high voltage and surge protection. The device allows for multiplexing of two USB sources onto the common DP/DM pins, while maintaining signal integrity. The device includes HV protection and offers IEC 64000-4-5 compliant surge protection up to ±20 volts, without the use of an external transient voltage suppressor (TVS).

The FSUSB242 is suitable for mobile applications, as it provides low power consumption, and saves board space with its WLCSP-9 package and elimination of the requirement for an external TVS.

The third device is the FUSB302BV, a USB-C controller designed specifically for power delivery (PD) solutions in automotive systems.

While other solutions are only available for consumer applications, this device is AEC-Q100 qualified and enables detection, including attach and orientation, making it one of the most efficient and flexible products available, says the firm.

Unlike other solutions, the FUSB302BV communicates via an I2C interface and does not integrate a microprocessor. This ensures the device meets the automotive requirements for minimal energy consumption and low levels of self-healing.

Commenting on the new releases, Julie Stultz, Product Marketing Manager, ON Semiconductor said, “In keeping with our mission to deliver energy efficient solutions to the market, all three products successfully combine high-performance with low power consumption. The ultra-small footprints make them ideal for mobile and ultra-portable applications while the AEC-Q100 qualified FUSB302BV represents a significant step forward in automotive USB solutions.”
