Introduction

Description
The DRV8432 is a dual full-bridge PWM motor driver. It has a maximum recommended supply voltage
of 52.5 V. The DRV8432 is capable of delivering 2 x 7-A continuous output current and 2 x 12-A peak
current per device. Furthermore, the outputs can be paralleled to drive 14-A continuous current or 24-A
peak current. The DRV8432 has an advanced protection system consisting of short-circuit protection,
overcurrent protection, undervoltage protection, and two-stage thermal protection.
The DRV8432EVM 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 an MCU controller module or signal generator. The outputs and power supplies are
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.
