Hello, to whom this may concern,
I am trying to develop a custom board using the DRV8305N and I'm facing some problems. Although nFault pin is high, I get no response on the output, except for a dc of 5.6v on every output pin.
Some infos about my hardware:
PVDD = 10v
INHA = PWM around 20kHz, 50% duty-cycle
INLA = INHB = INLB = INHC = INLC = 0 vols.
This setup consumes around 23 mA.
There's no Mosfet soldered yet, only the minimum hardware to get the driver working.
Please, I would like to understand what that means, I've tryed to apply 8v and 6v and all the outputs keep as 5.6v fixed. The driver emits a noise that resambles commutation, but there's no mosfet soldered, as I've said before.
