Bidirectional Motor Driver
Overview
The LB1830MC is a low-saturation bidirectional motor driver IC with brake function for use in low-voltage
applications.
As both of forward and reverse outputs are regulated, it is especially suited for use in portable equipment.
Features
• Wide operating voltage range: 3.0 to 9.0 V
• Low saturation voltage: 0.2V at IO = 40mA (typ)
• Low current drain at standby mode (0.1μA or less)
• Brake function
• Regulated voltage value (forward/reverse) setting available by one variable resistor
• Regulated output/saturation output switching available
• Built-in spark killer diodes
• Small package: SOIC10

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.

• The output voltage (voltage between output pins) Vo during drive with constant voltage is set as follows:
VO = (VC pin input voltage) × 2.4 (typical)
• There is no hierarchical relationship among voltages; VCC (control supply voltage), VS (motor supply voltage),
IN1/IN2 (input signal voltage).
