BP3621 (新產品)
Wide Range Type Wireless Charger Module (Power Transmission)

ROHM’s 13.56MHz wireless charging module is designed for compact sensor and wearable devices.
Wireless charging of ultra-small devices that are difficult to charge using the Qi standard is possible. And since 13.56MHz is the same frequency as the NFC communication standard, the same antenna can be used for both power supply and NFC transmission.
Pairing the BP3621 (power transmission) and BP3622 (power reception) modules significantly reduces customer development load for antenna design and matching.
