Software suite touts dynamic simulation for ST's VIPower tech

STMicroelectronics has revealed what it describes as a unique free software suite that includes a smart interactive selector and a dynamic electro-thermal simulator for automotive low/high-side driver/switches and H-bridges for motor control built using ST's proprietary VIPower technology. The TwisterSIM enables complex evaluations with accurate dynamic simulations of load-compatibility, wiring-harness optimisation, fault condition impact analysis, diagnostic behaviour analysis and dynamic thermal performance in just a few clicks, detailed the company.

TwisterSIM considerably reduces the cost and time needed to select and validate a product for a specific application layout by performing a thermal-electrical dynamic simulation.

The suite features a built-in library of accurate VIPower-product models based on a proprietary methodology and validation that allows a realistic reproduction of "in application" behaviour; a step-by-step guided selection of the optimal device for a specific application; a built-in load library for automotive lamps and generic loads; and direct links to the product web page to view related datasheet and product collaterals. In addition, simulation results, including junction thermal profiles, load current and diagnostic behaviour, are shown on dedicated scope views and can be exported in multiple commonly-used formats.

The TwisterSIM also boasts user-selectable wide range of environmental conditions and real device parameters.

The tool is free of charge and can be downloaded from the company's website.
