Fan Motor Driver

BD61243FV

General Description

Key Specifications

BD61243FV 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.
