L9110, The ASIC device control and drive motor design two-channel push-pull power amplifier discrete circuits integrated into a monolithic IC, peripheral devices and reduce the cost, improve the reliability of the whole. This chip has two TTL / CMOS compatible with the level of the input. With good resistance, two output terminals can directly forward and reverse movement of the drive motor. It has a large current driving capability, each channel through 750 ~ 800mA of continuous current, peak current capability up to 1.5 ~2.0A. More than enough for a small DC motor.
