Toshiba verifies thermal contribution in motor control driver ICs

High output current ICs usually generate a lot of heat from the driver transistor which affects the surrounding circuits. Therefore, it is important to take into account the transient heat based on the output current level when designing applications such as engine throttles or on/off switches for engine bulbs. In this whitepaper, the Toshiba team discusses how they used the Eldo circuit simulator's capability to perform fully-coupled electrothermal simulation for a DC motor driver IC to dynamically simulate temperature changes for optimizing all circuit parameters to achieve their required IC specifications.
