Does DRV8300DPWR provides phase to phase isolation ?
Does DRV8300DPWR provides input to output isolation?
How to test it without connecting MOSFETS??

Hey Aniket,

Each phase output is controlled by the corresponding input. So yes there is phase to phase isolation.

The INHx/Lx is connected first to internal logic and dead time insertion before going to the corresponding pre-drivers tied to the output. So, INHx/Lx is not directly connected to GHx/SHx if I am understanding your question correctly.

You can attach a 100kOhm resistor from GH/GLx to GND and toggle the inputs High/low to test this without the MOSFETS.

Hope this helps.

Best,

Akshay

HELLO AKSHAY,

1. WHAT ABOUT DEAD TIME IF ITS TSSOP 20 PIN PACKAGE.

2. I AM GETTING VOLTAGE AT GATE WITH RESPECT TO GROUND BUT NOT WITH RESPECT TO SOURCE.(WITHOUT MOSFETS).

3.AFTER PULLING GATE DOEN TO GROUND USING 100K WILL I GET VOLTAGE AT GATE WITH RESPECT TO SOURCE.

THANKS,

AKSHAY.

Hey Aniket,

Device has a fixed deadtime insertion of 200 nS for TSSOP package variants.

Best,
