Hello there
I'm currently using 4 DRV8848 chips to each drive four motors for a personal project of mine. I received my PCB board, soldered the components for the motor section, and manually shorted out the control pins and SLEEP pins to drive my motors. I noticed if I have the SLEEP pin (I've connected all of the DRV8848 SLEEP pins together) floating, my power supply shows a voltage drop after a few seconds of powering up the board. To prevent this from happening, I have to solder a wire from the SLEEP pin to the 3V3 rail to prevent this.
The DRV8848 internally has a pull down resistor for the SLEEP pins, so I should be able to directly connect this pin to my MCU. Any help would be ace. Here's a screenshot of my schematic:
