    The MDriver is a quadruple high-current half-H driver. It is designed to provide bi-directional drive currents of up to 600mA from 4.5 volts to 36 volts DC. This device is designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors in positive supply applications.


    The MDriver module is designed for use with the eLab6 microcontroller module for interfacing with small DC motors or solenoids. The module can be powered from the same 4.5 volt power supply as the eLab6 to control a small 3 volt motor. Higher voltage motors of 4.5 to 36 volts can be used with the MDriver by using a separate regulated supply connected to pin 8. A 220nF polyester capacitor has been connected directly across the motor terminals to prevent motor noise from interfering with the circuit.
