BD61245EFV
Multifunction Single-phase Full-wave Fan Motor Driver

BD61245EFV is a 1chip driver that is composed of H-bridge power DMOS FET. Moreover, the circuit configuration is restructured, and convenience has been improved by reducing the external parts and simplifying the setting compared with the conventional driver.
