Key Product Benefits
ST’s VIPower® family consists of a set of automotive-qualified high-side switches covering the full load range in terms of type and rated power and includes state-of-the-art embedded control functions and a brand-new protection mechanism. This offer represents the ideal solution for car systems such as junction boxes, interior/exterior lighting and DC motor driving as well as every application inside and outside the transportation domain requiring a protected 12V battery line
Benefits over a discrete design:
- Simpler design
- Lower bill-of-material
- Reduced board space
- Increased circuit reliability
- Reduced assembly costs
It is worth considering how to configure the drivers in a safe way. Indeed, in HSD mode, the current flows from a high-side source current to the load. While the low-side type connects or disconnects the load to ground.
Short-to-ground of the load is a more likely system failure mode compared to short-to-battery. This is the reason why a growing number of designers prefer HSD over LSD for their circuits.
These features are crucial in automotive applications, while they add value also in IoT applications, such as body warmers, gloves, jackets, bottle warmers, pail warmers, drawer warmer materials, tote heaters, tank and canister heaters, heated equine rugs, etc.
Smart Power high-side switches provide:
- Reduced switching losses for achieving better efficiency and better EMI performance
- Embedded protections avoiding device destruction due to excessive current, voltage, or temperature
- Means to return status information to the logic controller
