Hello!
I am interested in using the DRV8301 or DRV8302 for a 48V/60A brushless motor driver but I am not sure about the shoot through pretection of the device.
I would like to know how the shoot through protection works on the DRV8301/2 gate drivers.
The datasheet ( http://www.ti.com/lit/ds/symlink/drv8301.pdf states the following:
"Internal hand shake between high side and low side FETs during switching transition to prevent current shoot
through."
The addition of "during switching transition" throws me off.
I would like to know what happens when my input logic (PWM with six independent inputs) makes a fault and turns on both the LOW and HIGH input pins of a phase.
The initial dead-time control would prevent shoot-through, but what happens after this period?
Also what would happen if the HIGH input is high level and then the LOW side input goes high while keeping the HIGH input high.
And vice versa, LOW side is on and HIGH side is switched on while keeping the LOW side on.
Kind regards and thank you for your response,
Johan de Leeuw
