Ideal for use with PWM. It has in built protection to prevent all drive transistors switching on if both "Forward" and "Reverse" are activated at the same time. In this case the Motor will stop.\par \ql \x\fs20 \par \ql \x\fs20 The maximum drive current will depend on the transistors used\x\fs20 for Q5-8. The ones shown should supply up to 3A if mounted o\x\fs20 n heatsinks. If more current is required, then using Darlingt\x\fs20 on transistors for Q5-8 would be a better solution, such as T\x\fs20 IP122 and TIP142 work well.\par \ql \x\fs20 \par \ql \x\fs20 D1-4 are fast recovery diodes. These are essential to protect\x\fs20 the transistors from back E.M/F. spikes produced by the moto\x\fs20 r.
