Datasheet

STMicroelectronics has announced TwisterSIM, a unique free software suite that includes a smart interactive selector and a dynamic electro-thermal simulator. The TwisterSIM electro-thermal simulator eases the evaluation of ST’s low and high-side drivers and H-bridges for motor control through accurate simulations 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.

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.

Key features include:

Built-in library of accurate VIPower-product models based on a proprietary methodology and validation that allows a realistic reproduction of 'in application' behaviour;
Step-by-step guided selection of the optimal device for a specific application;
Built-in load library for automotive lamps and generic loads;
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;
User selectable wide range of environmental conditions and real device parameters;
Direct links to the product web page to view related datasheet and product collaterals; and
On-line forum available at www.st.com/twistersim-forum.

The TwisterSIM tool can be downloaded free of charge from the ST website.
