STMicroelectronics offers a wide range of automotive-grade 3- and 5-pin low-side switches based on the company’s VIPower (vertical intelligent power) technology. This proprietary technology allows integration of complete digital and analog control and protection circuits driving a vertical power MOSFET, all on the same chip.
With its OmniFET III series based on VIPower M0-5 technology, ST offers a power limitation overload protection scheme that limits the current below the higher threshold during inrush, while reducing the threshold to a lower value during thermal cycling, so limiting thermal stresses and increasing the global lifetime of the device.
Designed to work from -40°C to +150°C, the product portfolio includes single and dual drivers with digital status and on-resistance values ranging from 10 m to 300 m. Furthermore, with their open load and short circuits to VCC detection, active even with the device in the off-state, these low-side drivers are a safe way to drive and protect a lamp or any other load in a car.
