Image of ROHM Semiconductor BP3621/BP3622 Wireless Charger ModulesROHM’s BP3621 13.56 MHz wireless charging module is designed for compact sensors and wearable devices. Pairing the BP3621 (power transmission) and BP3622 (power reception) modules significantly reduces the customer's development load for antenna design and matching.

Wireless charging of ultra-small devices that are difficult to charge using the Qi standard is possible. Since 13.56 MHz is the same frequency as the NFC communication standard, the same antenna can be used for both power supply and NFC transmission.

Features
  • BP3621: power transmitter
  • BP3622: power reception
  • The BP3621 is optimized for wireless charging with BP3622
  • 212 kbps wireless communication
Applications
  • Compact sensors
  • Wearable devices
