LB1846MC Bidirectional Motor Driver Evaluation Board

The LB1846MC is a single-channel low saturation voltage stepping motor driver IC. It is optimal for motor drive in 5V system products and it can drive a stepping motor in Full-step and Half-step. Also LB1846MC is suitable for use with gas burner for its latch valve drive. The latch valve functions as a safety device to prevent gas leakage.

Saturation drive H bridge: 4 channels

Built-in thermal protection circuit

Built-in low voltage malfunction prevention circuit

Incorporates a transistor for driving photo sensors

BIP output transistor adoption(Upper and lower total Vo(sat)=0.55V(typical) at Io=400mA)

For one power supply (The control system power supply is unnecessary.)
