STMicroelectronics Extends USB Fast
Charging over USB-C® to Embedded Applications with USB-IF-Certified
Development Board
- USB-IF-certified solution provides solid reference for
end-product certification
- Promotes reuse and reliable interoperability for existing
USB-C® fast chargers and cables with USB Power Delivery
support
- Enables cost-effective system partitioning leveraging on-chip
integrated features unique to ST
Geneva, June 29, 2020 – STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers
across the spectrum of electronics applications, is facilitating
modernization of battery-powered products to capture the advantages
of the latest USB Power Delivery (USB PD) technology including
faster charging and easy reuse of USB-C® chargers and cables. The
universal fast-charging ecosystem is rapidly expanding as products
like mobile handsets gain ever-larger batteries. The latest USB PD
chargers can have power ratings up to 100W and can optimize
charging by dynamically adjusting current and voltage thanks to the
USB Programmable Power Supply (PPS) feature of USB PD. A huge
diversity of products such as smart speakers, power tools,
wearables, robots, gaming controllers, power banks, and drones --
traditionally recharged at 5V through older USB micro-B or
proprietary connectors -- can now leverage this ecosystem to
benefit from the advantages and interoperability of USB-C
technology while charging faster. To support this migration, ST has
created a USB Implementers Forum (USB-IF) certified evaluation
board for up to 100W PPS USB Power Sinking Devices (PSD) that helps
developers accelerate new designs and supports certification of the
end product.
“Using our USB-IF-certified development board, customers can now
quickly add all of the USB-C benefits and reuse a solid platform
for certification of their own board, contributing to a safe and
reliable USB Type-C and USB PD ecosystem,” said Ricardo de Sa Earp,
Group Vice President, Microcontrollers Division General Manager,
STMicroelectronics.
“The unmatched capabilities of USB PD over USB Type-C cables and
connectors is driving rapid innovation in a variety of USB charging
applications and markets,” said Jeff Ravencraft, USB-IF President
and COO. “Inventive solutions, such as ST’s new evaluation board,
are vital to support the continued growth of USB-IF-certified USB
PD and USB Type-C devices that consumers can rely on.”
The certified device (USB-IF TID: 3036) combines ST’s
Nucleo-G071RB and X-Nucleo-USBPDM1 development boards. The
Nucleo-G071RB features an STM32G0 microcontroller, the industry’s
first general-purpose microcontroller to integrate a USB Type-C
Power Delivery controller on-chip, enabling greater system
integration as well as the possibility to support new application
use cases. The X-Nucleo-USBPDM1 board contains ST’s TCPP01-M12
companion chip for port protection.
Moreover, customers can leverage the powerful tools and software
of the STM32 ecosystem to complete their projects quickly and
easily. Applications already using a microcontroller with legacy 5V
USB charging can be updated to USB Type-C with only a small number
of external components.
The Nucleo-G071RB ($10.32) and X-Nucleo-USBPDM1 ($23.50) are
available now from st.com or distributors.
Further technical information The STM32G0 MCU
and TCPP01-M12 enable an efficient and economical two-chip solution
capable of controlling and protecting the USB PD capable USB Type-C
port as well as hosting the embedded application.
The TCPP01-M12 companion high-voltage analog front end
integrates a charge pump to control the gate of an external power
switch, which lets designers choose from economical N-channel
MOSFETs that have lower RDS(on) than P-channel alternatives. There
is also a low-power mode that draws 0nA when no cable is attached,
enabling longer battery runtime.
The protection features built into the TCPP01-M12 include
adjustable 5V to 22V overvoltage protection on VBUS, short-to-VBUS
protection on configuration channel pins, dead-battery management,
and IEC 61000-4-2 ESD protection up to ±8kV on VBUS and CC
lines. The TCPP01-M12’s QFN12 package occupies 80% less board
space than a discrete implementation.
