Need to drive a >30V (several amps) coil but back off once it's on to
avoid a cook-out. This needs to be PWM'd because the drive electronics
can't get hot at all. So I looked at coil driver chips. DRV103 and the
like. Many can't stomach more than 32V which is borderline for me and
the saturation voltage respectively Rdson values, well, yawn. Nothing to
write home about.
Did I miss a really good chip? Else I'll just roll my own.
