2 Total Dose Test Setup

The DRV8351-SEP was set up with PVDD and GVDD powered up to 15V and 40V respectively. The inputs (INLx and INHx) were all tied together. DRV8351-SEP has a 3x PWM mode such that given a high side input, the low side automatically inverts the signals such that a motor can be driven with 3 signals versus the 6 required from a non inverting device. The switching frequency Fs = 100kHz, switching from 0V to 5V.
