Texas Instruments DRV8432 | Demoboard DRV8432EVM

Beschreibung

The DRV8432 is a dual full bridge PWM motor driver. It has a maximum recommended supply voltage of 52V and is capable of delivering 2x7A continuous output current and 2x12A peak current per device. 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 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
