Product Description
STMicroelectronics VN7050ASTR is a high-performance Motor Driver IC designed for automotive power management applications, offering a 21A output current with a minimum and maximum supply voltage of 38V.
The chip is implemented as a single channel smart high-side driver with MultiSense analog feedback, manufactured using ST's proprietary VI Power M0-7 technology. It is packaged in an 8-pin SO type, making it suitable for compact automotive electronic designs.
Designed to drive 12V automotive grounded loads, the VN7050ASTR accepts both 3V and 5V CMOS-compatible inputs, providing versatile interfacing options for embedded control systems.
This device includes advanced diagnostic and protection features such as thermal shutdown indication, overload and short-to-ground power limitation, undervoltage shutdown, overvoltage clamp, and off-state open-load detection. It ensures operational safety and reliability in demanding automotive environments.
The VN7050ASTR operates over a wide temperature range from -40°C to 150°C, fulfilling rigorous automotive application standards including AEC-Q100 certification. Additional protections include reverse battery protection using external components and robust electrostatic discharge protection to safeguard the device and connected systems.
This motor driver integrates Smart high-side driving with MultiSense analog feedback for precise current monitoring. Low standby current reduces power consumption when not in active switching state. Diagnostic capabilities enhance system reliability and maintenance.
Compact 8-pin SO package supports high integration density in automotive electronics. Wide temperature and voltage operating ranges enable use in harsh environments.
Suitable for use in automotive, industrial motor control, and other power management applications, the VN7050ASTR supports modern embedded system designs requiring robust, protected, and diagnostic motor driving capability.
