STEVAL-VNH5019A STMicroelectronics

STEVAL-VNH5019A Motor driver evaluation board based on VNH5019A Data brief Description STEVAL-VNH5019A offers dedicated power stage and controls suitable for electric DC motor driving. This evaluation board comes pre-assembled with VNH5019A H-bridge belonging to the VNH Motor Driver series based on VIPower proprietary technology. Typical applications are Windows Lift, Sliding Door, Seat regulation. This Evaluation Board consists of a motherboard (STM8 Universal Board) and a daughterboard. Features The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the VNH5019A assembled Type R I V DS(on) out CC(max) in the daughterboard. 18 m typ VNH5019A-E 30 A 41 V With the aim to make simpler the board usage (per leg) and settings, ST provides a dedicated and user- friendly software with a Graphic User Interface Handling up to 30 A of maximum motor current (GUI). This enables the user to set VNH5019A output parameters (PWM, Motor direction) and at the same time it shows real time device diagnostic Undervoltage and overvoltage shutdown information like current output evolution, battery Device thermal protection voltage monitoring, board temperature and much Cross-conduction protection more. 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 VNH5019A current sense output) On-board charge pump output for reverse polarity protection Device output protected against short to Table 1.
