STEVAL-ISB038V1T：1 W wearable wireless power transmitter based on STWBC-WA
STEVAL-ISB038V1T is the wireless battery charger transmitter module in the
STEVAL-ISB038V1 Reference Design Kit.
The STEVAL-ISB038V1 is a wireless battery charger evaluation kit designed for
ultra-compact battery operated devices such as wearable gear, smartwatches, Internet Of
Things sensors, medical devices, etc.
The kit supports wireless power transfer of 1 Watt over an 11 mm coil on the receiver
side and 20 mm on transmitter side.
The kit configuration delivers 1 Watt of power at the receiver side.
While the Kit is configured to support low power (1 W) applications, it can support up to
3 W applications with wider coils or by switching to full-bridge configuration on the
transmitters.
The STWBC-WA transmitter is based on a cost-effective half bridge topology (full-bridge
optional) offering the flexibility of a powerful software API allowing LED and GPIO
control, as well as adding external interfaces via I²C and UART communication ports.
