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.
