STMicroelectronics Motor Driver IC 21 A 8-Pin 38V VN7050ASTR

STMicroelectronics VN7050ASTR is a highly reliable Motor Driver IC designed to deliver 21 A output current through an 8-pin small-outline (SO) package. Powered by ST proprietary VI Power M0-7 technology, this device is tailored for automotive applications, providing protection and diagnostic functionalities essential for modern vehicle electronic systems.

This single channel high-side driver integrates MultiSense analog feedback for precise monitoring and control of motor loads. It interfaces seamlessly with both 3 V and 5 V CMOS logic levels, making it versatile for various control systems.

The driver features comprehensive protection including thermal shutdown to prevent damage under overheating, overload and short-to-ground power limitation indications, and undervoltage shutdown to ensure safe operation. An overvoltage clamp safeguards the device against voltage spikes, while the self-limiting of fast thermal transients enhances longevity under dynamic load conditions.

Designed for harsh environments, the VN7050ASTR operates reliably over a wide temperature range from -40°C to 150°C and meets the automotive industry standard AEC-Q100, guaranteeing quality and durability. Electrostatic discharge protection extends device robustness against handling risks.

Its reverse battery protection capability, with the use of external components, provides an additional safety layer for automotive power systems. These features make the VN7050ASTR ideal for powering 12 V automotive grounded loads with high efficiency and protection.

Applications for this motor driver IC include automotive electronic control units, industrial motor control, and other systems requiring intelligent, safe high-side driving capabilities. The device package is compact and suitable for integration in space-constrained designs.
