1 Introduction

1.1 Description

The DRV8412 is a dual full bridge PWM motor driver. It has a maximum recommended supply voltage

of 50V with an absolute maximum of 70V. The DRV8412 is capable of delivering 2x3A continuous

output current and 2x6A peak current per device. The DRV8412 has an advanced protection system

consisting of short-circuit protection, overcurrent protection, undervoltage protection, and two-stage

thermal protection.

The DRV8412EVM can be operated with either two full bridge outputs or 4 half bridge outputs. It can

also be used in parallel mode to double the current capability. The unit can be operated with external

PWM inputs using a MCU controller module or signal generator, etc. The outputs and power supplies

can be connected using stripped wires by connecting them to the on-board terminal blocks. The EVM

module also has hardware switches to control the modes and to allow a manual reset.

1.2 DRV8412EVM Features

• PWM input motor driver module

• Self-contained protection system (short-circuit and thermal)

• Double-side, plated-through PCB layout
