Part Number:DRV8870
Hi,
in medical application customers need any kind of protection and not always it is easy to find the right solution.
For example, I was asked to suggest something to avoid that due to simultaneous internal short circuit of the high side and low side of different legs , the motor runs without control.
For your info now they have some relais, more than one, to protect this situation, even if this solution is not 100% sure, because it may happen that also all relays get shorted simultaneously, but in this case probability it may happen is quite low.
Maybe this is a question for QA people, but what is the probability that 2 internal mosfets get shorted.
Any idea or solution?
Thanks
Umberto
