The LB1973M 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

• The range of the operation voltage is wide.(1.8V to 7.5V)

• Small package : MFP10S(225mil)

• Built-in thermal protection
