                VNH5050A评估板:适用于直流电动机的驱动,应用于双清洗泵和阀座调节

                STEVAL-VNH5050A

                 
                设计简介

                STEVAL-VNH5050A offers dedicated power stage and controls suitable for electric DC motor driving. This evaluation board comes pre-assembled with VNH5050A H-bridge belonging to the VNH Motor Driver series based on VIPower?proprietary technology. Typical applications are dual washer pump and seat regulation.

                This evaluation board consists of a motherboard (STM8 Universal Board) and a daughterboard.
                The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the VNH5050A assembled in the daughterboard.
                With the aim to make simpler the board usage and settings, ST provides a dedicated and user-friendly software with a Graphic User Interface (GUI). This enables the user to set VNH5050A parameters (PWM, Motor direction…) and at the same time it shows real time device diagnostic information like current output evolution, battery voltage monitoring, board temperature and much more.

                主要特性

                • Handling up to 30 A of maximum motor current output
                • Undervoltage and overvoltage shutdown
                • Overvoltage clamp
                • Device thermal protection
                • Cross-conduction protection
                • Current and power limitation
                • Very low standby power consumption
                • Programmable PWM operation (up to 20 kHz)
                • Protection against loss of ground and loss of VCC
                • Motor current monitoring (thanks to VNH5050A current sense output)
                • Device output protected against short to ground and short to VCC
                • Graphic User Interface (GUI)
