STEVAL-VNH5180A STMicroelectronics

STEVAL-VNH5180A Motor driver evaluation board based on VNH5180A Data brief Description STEVAL-VNH5180A offers dedicated power stage and controls suitable for electric DC motor driving. This evaluation board comes pre-assembled with VNH5180A H-bridge belonging to the VNH Motor Driver series based on VIPower proprietary technology. A typical application is the door lock. This evaluation board consists of a motherboard (STM8 Universal Board) and a daughterboard. The motherboard, based on STM8 microcontroller, provides the logic section for Features monitoring and driving the VNH5180A assembled in the daughterboard. Type R I V DS(on) out CC(max) With the aim to make simpler the board usage and settings, ST provides a dedicated and user- 180 m max VNH5180A-E 8A 41V friendly software with a Graphic User Interface (per leg) (GUI). This enables the user to set VNH5180A parameters (PWM, Motor direction) and at the Handling up to 8 A of maximum motor current same time it shows real time device diagnostic output information like current output evolution, battery voltage monitoring, board temperature and much Undervoltage shutdown more. 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 V CC Motor current monitoring (thanks to VNH5180A current sense output) Device output protected against short to Table 1.
