Description

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.
