Overview
The LB1947VC is a PWM current control type forward/reverse motor driver IC. The IC is optimal for use in driving
brushed DC motors for printers.
Features
• PWM current control (fixed OFF time)
• Selectable current decay pattern (FAST, SLOW, and MIX DECAY modes)
• Simultaneous ON prevention function (feed-through current prevention)
• Built-in thermal shutdown circuit
• Built-in noise canceler

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.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
