Geneva, November
29, 2022 –
STMicroelectronics (NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics
applications, has revealed a wireless power receiver with the
industry’s highest available power rating of 100 Watts. Ensuring
the fastest wireless charging times in the market today, ST’s new
STWLC99 device can recharge high-end smartphones with the largest
battery capacity in less than 30 minutes.
“Today’s phones are essential for digital living, as well as
being a critical business tool for many. Significantly faster
charging with our STWLC99 increases their availability and brings
extra value to users’ lives,” said Francesco Italia, General
Manager, Analog Custom Products Division, STMicroelectronics. “Its
unprecedented power also changes the outlook for equipment such as
battery-powered industrial tools, medical monitors, medicine pumps,
mobile robots, and drones, enabling long runtimes with faster
turnaround.”
In addition to enhancing user convenience, high-power wireless
charging lets designers create industrial products that are free of
power sockets and cords, which can deliver various advantages.
Eliminating the charging socket can save space and allow sealing
against water or dust ingress in challenging environments.
Complications due to twisting or tangling of the cord can be
avoided. Independently mobile devices such as robots and drones can
recharge easily without a mechanism or human intervention to
connect the cable.
Housed in a 4.859m x 4.859mm wafer-level chip-scale package
(WLCSP), the STWLC99 is in production now and available from
$2.50.
Further technical information:
With an energy-efficient architecture comprising a synchronous
rectifier with MOSFETs of low RDS(on) and a low-dropout regulator,
the STWLC99 directs the received energy to the charging battery
with minimal loss and low thermal dissipation.
Compliant with Qi 1.2.4 and 1.3, it supports the Qi Extended
Power Profile (EPP) and leverages ST’s specially optimized
STSuperCharge (STSC) protocol for fast charging. The battery
charging power reaches up to 100W when combined with ST’s STWBC2-HP
transmitter solution.
The STWLC99 contains non-volatile memory for storing
configuration parameters and provides an I2C interface for
exchanging configuration data and charging control. A comprehensive
set of safety features is built in, including foreign object
detection with accurate current sensing, Q-factor detection in
transmit mode, and overcurrent, overvoltage, and thermal
protection.
STWLC99 is also capable of operating as a power transmitter up
to 25W for charging other devices.
