Hi everyone,
I'm evaluating a driver IC for a student project and found the DRV8313. It seems to match my requirements quite nicely, but two things are not completely clear to me after studying the datasheet:
- What is the maximum switching frequency at which the device operates correctly? The DS states a propagation delay of 475ns/500ns, but if it is just a delay, then this would not really limit the switching frequency.
- What is the maximum on-time of the high-side FET? The device does not use bootstrapping capacitors but a dedicated charge-pump, so is it possible that the device can keep the output high for an indefinite time?
Thanks,
Philipp
