STEVAL-ISB038V1

Оценочная плата, STWLC04 и STWBC-WA беспроводной приемник и передатчик питания носимых устройств.

The STEVAL-ISB038V1 is a 1W wearable wireless power system based on STWBC-WA and STWLC04 modules. This wireless battery charger evaluation kit is designed for ultra compact battery operated devices such as wearable gear, smart watches and IoT sensors. The kit supports wireless power transfer of 1W over an 11mm coil on receiver side and 20mm on transmitter side. The kit configuration delivers 1W of power at receiver side. While kit is configured to support low power (1W) applications & can support up to 3W applications with wider coils or by switching to full bridge configuration on transmitters. The STWBC-WA transmitter offers flexibility in terms of offering a powerful software API which allows to modifying behaviour of LED and GPIOs as well as adding external interfaces via I2C and UART ports. The STWLC04 is focused on 1W protocol based on Qi.Digital control and precise analogue control loops assure stable operation. I2C interface allows many parameters to be customized in device

• USB 5V input
• Optional foreign object detection (FOD)
• Graphical interface for monitoring behaviour
• Cost effective half bridge topology with integrated drivers
• Optional full bridge configuration for 3W applications
• Active presence detector and two layer PCB for easy design
• Turnkey solution or customizable via APIs and parametric customization via graphical interface
• Receiver with integrated high efficiency synchronous rectifier
• 5V regulated output voltage at receiver
• Li-ion/Li-pol charger functionality, 4 layer PCB to facilitate design
