LB1846MC: Bidirectional Motor Driver, Low Voltage, Low Saturation

The LB1846MC is 2-channel low-voltage, low saturation voltage type bidirectional motor driver IC that is optimal for use as 2-phase stepping motor drivers in printers, cameras and other portable equipment. The output circuits are of the bipolar type, with PNP transistors in the upper side and NPN transistors in the lower side, and they achieve low saturation output and low power characteristics despite being provided in a miniature package. The LB1846MC products can directly control a motor from signals from a microcontroller. The LB1846MC is optimal for 1-2 phase excitation drive for 2-phase stepping motors using 4-input logic (IN1, IN2, IN3 and IN4). Another point is that these IC include built-in thermal shutdown circuits so that IC scorching or burning is prevented in advance even if the IC output is shorted.

Features
  • Low voltage and wide operation
  • Small Package
  • Low saturation voltage. VO (sat) = 0.55V typical at IO = 400mA
  • No limitations on the magnitude relationship between the power supply voltage (VCC) and the input voltage (VIN)
  • Standby current: Zero
  • Thermal shutdown circuit
Benefits
  • portable devices available
  • Reduction of substrate size
