61295HA(II) No.3948-1/6 Semiconductor Components Industries, LLC, 2013 November, 2013 http://onsemi.com LB1837M 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.

No.3948-4/6 Pin Functions Pin No. Symbol Equivalent Circuit Diagram Pin Function 14 VCC Power supply pin for output and controller. GND GND pins for output and controller. Both must be grounded. IN2 IN1 IN3 IN4 Input pins that determine the excitation of the outputs. IN1 and IN2 control outputs OUT1 and OUT2; IN3 and IN4 control outputs OUT3 and OUT4. When inputs IN1 through IN4 are all low or open, the device goes into standby mode and current consumption drops to 10 μA or less. L: –0.3 to +0.7 V H: 3.0 to 9.0 V There are no limitations on the magnitude relationships between the V CC and VIN supply voltages. OUT4 OUT3 OUT1 OUT2 Output pins. Have built-in spark killer diodes. Braking provides short braking that turns on the lower transistor.
