Overview
The LB1837M is a low-voltage, low-saturation, two-channel
motor driver with a bidirectional braking function that provides
constant-voltage regulated output for bidirectional operation.
The design of the LB1837M is ideal for video equipment,
cameras, and other portable equipment.
Function
• Wide operating voltage range (3.0 to 9.0 V).
• Low saturation voltage
VO (sat) = 0.40 V at IO = 200 mA.
• Consumes almost no current in standby mode (0.1 μA or less).
• Permits setting of bidirectional constant-voltage regulated value.
• Built-in reference voltage coupled to input.
• Brake function built in.
• Compact MFP14S package.
