STMicroelectronics STEVAL-VHN5019A Evaluation Board
STMicroelectronics STEVAL-VHN5019A Evaluation Board offers dedicated power stage and controls suitable for electric DC motor driving. This evaluation board comes pre-assembled with a VNH5019A H-bridge belonging to the VNH Motor Driver series based on VIPower® proprietary technology. Typical applications are window lifts, sliding door, and seat regulation. This Evaluation Board consists of a Motherboard (STM8 Universal Board) and a Daughterboard.
The Motherboard, based on the STM8 microcontroller, provides the logic section for monitoring and driving the VNH5019A pre-installed on the Daughterboard. STMicroelectronics provides a dedicated and user-friendly software with a Graphic User Interface (GUI) which enables the user to easily set the VNH5019A parameters, such as PWM and motor direction. The GUI also shows real-time device diagnostic information like current output evolution, battery voltage monitoring, board temperature, and much more.
Features
- Handles up to 30A of maximum motor current output
- Undervoltage and overvoltage shutdown
- Device thermal protection
- Cross-conduction protection
- Very low standby power consumption
- Programmable PWM operation (up to 20kHz)
- Protection against loss of ground and loss of VCC
- Motor current monitoring (thanks to VNH5019A current sense output)
- On-board charge pump output for reverse polarity protection
- Device output protected against short to ground and short to VCC
- Graphic User Interface (GUI)
