STEVAL-VNH5050A STMicroelectronics

STEVAL-VNH5050A Motor driver evaluation board based on VNH5050A Data brief Description 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 Features microcontroller, provides the logic section for monitoring and driving the VNH5050A assembled in the daughterboard. Type R I V DS(on) out CC(max) With the aim to make simpler the board usage 50 m max VNH5050A-E 30 A 41 V and settings, ST provides a dedicated and user- (per leg) friendly software with a Graphic User Interface (GUI). This enables the user to set VNH5050A Handling up to 30 A of maximum motor current parameters (PWM, Motor direction) and at the output same time it shows real time device diagnostic information like current output evolution, battery Undervoltage and overvoltage shutdown voltage monitoring, board temperature and much Overvoltage clamp more. 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 V CC Motor current monitoring (thanks to VNH5050A current sense output) Device output protected against short to ground and short to V CC Table 1.
