PwrCtrl signal

Does the HBL2360 require a relay for the PwrCtrl signal.

When PwrCtrl is connected to ground, a current of less than 1mA flows through it. So can we use a transistor? It's more reliable and cost-effective than a relay.

(We have no wish to apply power to the HBL2360 via the PwrCtrl lead so we don't need changeover contacts. We will simply connect PwrCtrl to ground to turn off the controller.)

You can just wire up a switch to power control and ground. When power control is floating, current can flow through vmot power source. When it is shorted to ground, it cuts off power going into vmot(power off on controller).

We need to control it from a microprocessor.

I don't see the harm in doing so.

I'll try it and see. I'll let you know how I get on.

Thanks.
