- STMicroelectronics informed that this controller is certified for pure 5V sink-only applications
- The company is retailing these in two different chip-scale packages
- USB-C is rapidly becoming established as a replacement for Micro-B or Mini-B plugs
STMicroelectronics (STMi) has announced the launch of STUSB4500L. Latest addition to company’s USB-C controller IC family, STMi informed that it is designed and certified for pure 5V sink-only applications.
“All mandatory features to use the USB-C connector as a 5V universal power plug are integrated, allowing designers to implement USB-C charging solutions quickly and easily without studying the standard or writing code,” read STMi’s official statement.
The STUSB4500L, as the company informed, is in production now, in a choice of 4mm x 4mm QFN-24 package or 2.6mm x 2.6mm CSP-25 chip-scale package. STMi is retailing these at $0.70 and $0.75 respectively, for orders of 1000 pieces.
Low-voltage applications such as Bluetooth speakers, computer accessories
STMi’s new USB-C controller IC is a stand-alone, plug-and-play interface product, targeting low-voltage applications such as Bluetooth speakers, computer accessories, Wi-Fi access points, point-of-sale equipment, LED lighting, and USB dongles. The company informed that it can also be used for powering equipment such as single-board computers and hardware development kits.
“The controller IC runs without additional code and requires no external support from the microcontroller, which eases adoption of the USB-C connector standard by saving time-consuming design work,” read STMi’s official statement.
It continued, “The STUSB4500L is auto-powered via VBUS from the connected source and does not need to be supplied from a local battery or on-board power. Zero leakage current prevents draining the battery when not charging. Input over-voltage protection prevents low-voltage equipment being damaged if it is incorrectly connected, for example, to a 20V source from a USB PD AC adapter rather than the required 5V supply.”
It also features dead-battery support to ensure correct identification by the source when the battery is fully discharged, true cold-socket implementation which keeps the VBUS switch open by default until safe 5V input power is supplied, source power-budget identification and error-recovery support to ensure correct re-starting when a fault is triggered.
“To ease prototyping, the reference design EVAL-SCS002V1, which has a small footprint of just 2.5 cm², can be ordered from ST or distributors. For fast implementation into proprietary designs, the full PCB design libraries can be downloaded free of charge from STMi’s website,” informed the company.
