Product highlights


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

VIPower high-side drivers integrate digital control, output sensing, diagnostics, and protection features (overload/overcurrent/over-temperature/overvoltage).

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.
