STMicroelectronics VNH5xx VNH7xx Automotive H-Bridge Drivers

STMicroelectronics VNH Automotive H-Bridge Drivers

STMicroelectronics VNH Automotive H-Bridge Drivers are integrated H-bridges that are intended for a wide range of automotive applications driving DC motors. The device incorporates a dual monolithic high-side driver and two low-side switches. All switches are designed using STMicroelectronics® well known and proven proprietary VIPower® M0 technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuitry. These packages, specifically designed for the harsh automotive environment, offer improved thermal performance thanks to exposed die pads. Moreover, their fully symmetrical mechanical design allows superior manufacturability at board level.

Evaluation Boards and Development Tools

STMicroelectronics offers a number of different evaluation boards and development tools for use with the VNH Automotive H-Bridge Drivers. They are each preassembled with the specific high-side driver. The EV-VNH5050A and EV-VNH5180A are designed to drive 12V automotive bidirectional load such as a PMDC motor. The STEVAL-VNH5019A / STEVAL-VNH5050A / STEVAL-VNH5180A Motor Driver Evaluation Boards offer dedicated power stage and controls suitable for electric DC motor driving.


STMicroelectronics EV-VNH5050A / EV-VNH5180A Evaluation Boards

STMicroelectronics EV-VNH5050A / EV-VNH5180A Evaluation Boards provide you an easy way to connect ST’s surface mounted VIPower® H-Bridge drivers into your existing prototype circuitry. This evaluation board comes preassembled with VNH5050A-E or VNH5180A-E high-side driver. These evaluation boards are a system in package H-Bridge manufactured in the ST proprietary VIPower M0-5 technology and housed in the PowerSSO-36 package. Each is designed to drive 12V automotive bidirectional load such as a PMDC motor. They provide protection, diagnostics and easy 3V and 5V CMOS compatible interface with any microcontroller. Each device integrates advanced protection functions such as load current limitation, inrush and active overload management by power limitation, over-temperature shut-off with auto restart and over-voltage active clamp. A dedicated analog current sense pin is associated with every output channel in order to provide enhanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to Vcc protection and diagnosis as well as ON & OFF state open-load detection.

STMicroelectronics STEVAL-VNH5019A/STEVAL-VNH5050A/STEVAL-VNH5180A Motor Driver Evaluation Boards

STMicroelectronics STEVAL-VNH5019A / STEVAL-VNH5050A / STEVAL-VNH5180A Motor Driver Evaluation Boards offer dedicated power stage and controls suitable for electric DC motor driving. These evaluation boards come pre-assembled with either a VNH5019A, VNH5050A or VNH5180A H-bridge belonging to the VNH Motor Driver series based on VIPower® proprietary technology. Typical applications are windows lift, sliding door, dual washer pump, and seat regulation. Each of these evaluation boards consist of a motherboard (STM8 Universal Board) and a daughterboard. The motherboard, based on STM8 microcontroller, provides the logic section for monitoring and driving the H-bridge 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 the H-bridge 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.
