Monolithic Digital IC
Two-channel H-Bridge Driver
LB1973JA
Overview
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.
Features
• Two-channel H-bridge driver
• 2ch simultaneous connection is possible
• Parallel input interface
• 2 phase excitation, 1-2 phase excitation drive are possible
• The range of the operation voltage is wide.(1.8V to 7.5V)
• Built-in thermal protection

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high
voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
