Product Description
STMicroelectronics VN7050ASTR Motor Driver IC is a high-performance single channel smart high-side driver specifically engineered for automotive applications. Operating at a supply voltage of 38V, this 8-pin SO package device supports an output current of 21A, efficiently driving 12 V automotive grounded loads through CMOS-compatible 3 V and 5 V interfaces.
Manufactured using ST proprietary VI Power M0-7 technology, the IC integrates multiple protection and diagnostic features to ensure robust and reliable operation under harsh automotive conditions. It provides precise MultiSense analog feedback for load monitoring and adheres to the Automotive AEC-Q100 standard for quality and reliability.
Key functional protections include overload and short-to-ground power limitation indication, thermal shutdown, off-state open-load detection, undervoltage shutdown, overvoltage clamp, and load current limitation. The device also features self-limiting fast thermal transients and reverse battery protection when used with external components.
This Motor Driver IC is suitable for use in a wide range of automotive and industrial electronics systems requiring high-current load switching and precise diagnostics, including motor control, lamp control, and solenoid drivers.
Supports high-side driving for 12 V automotive loads with built-in diagnostics. Low standby current optimizes system power consumption. Thermal and electrical protections safeguard both device and load. Reverse battery protection enhances system robustness.
Compliant with automotive-grade quality standards (AEC-Q100). The VN7050ASTR device is packaged in a compact SO-8 form factor, facilitating easy PCB integration and space-saving design.
EnvMart offers this product as part of its comprehensive selection of electronic components for automotive and industrial uses, supporting engineering, manufacturing, and maintenance requirements.
