STMicroelectronics STWBC-WA, Battery Charge Controller IC, 3 mA, 7.75 mA 32-Pin, VFQFPN


STMicroelectronics STWBC-WA wireless battery charger transmitter application optimized for wearable usage. Thanks to its 5 V native supply, the STWBC-WA device is ideal to operate with USB power supplies. Wireless battery charging systems replace the traditional power supply cable by means of electromagnetic induction between a transmitting pad or dongle (TX) and a battery-powered unit (RX), such as a smartwatch or sports gear. The power transmitter unit is responsible for controlling the transmitting coil and generating the correct amount of power requested by the receiver unit.
