DRV830x Rev D. Hardware Quick Start Guide
Version 1.0.5
Motor Solutions
Fig 1: DRV830x EVM with controlCARD
Abstract
The Low Voltage, High Current Motor Drive EVM (DRV8301, Figure 1), provides a great way to
learn and experiment with digital control of sub 60 volt three-phase motors to increase efficiency
of operation. The board is available in two configurations, the DRV8301 or the DRV8302. This
document goes over the typical kit contents and hardware details, and explains the functions and
locations of jumpers and connectors present on the board. This document supersedes all the
documents available for the kit.

A bootstrap capacitor under voltage protection circuit (BST_UVP) will start under this circumstance to prevent the potential failure of the high-side MOSFET. In this circumstance, both the FAULT and OTW pins should pull low and the device should self-protect itself. - Page 7 Fig2: DRV830x-EVM Board Macros...

Page 8: Powering The Board
Powering the Board The board is separated into two power domains*, the low voltage Controller Power domain that powers the controller and the logic circuit present on the board, and the medium voltage power delivery line that is used to carry the medium voltage and current like the DC power for the Inverter also referred to as DC Bus. -

Page 16: Optimizing Sense Circuitry
Optimizing Sense Circuitry Overview Proper resolution of motor signals is critical to the performance of any control system, but especially those with software observers attempting to replace the precision of an absolute encoder. Because the DRV83xx are built to work at over 50 Vdc-bus, the resolution of the voltage sensing is not as precise as you would like for motors <... -
