The LB1973JA is a two-channel H-bridge driver that supports for low saturation draive operation. It is optimal for

H-bridge drive of stepping motors (AF and zoom) in portable equipment such as camera cell phones.

• Two-channel H-bridge driver

• 2ch simultaneous connection is possible

• Parallel input interface
