The SIM2-151A is a high-voltage 3-phase motor driver in which transistors, pre-drive circuits, and bootstrap circuits (diodes and resistors) are highly integrated in a compact DIP40 package.
Along with the lower-loss power elements, SIM2 successfully reduced the product’s mold volume by 40% or more compared to our conventional package through the DCB (Direct Copper Bonding) structure—whose excellent heat dissipation is a promising feature.
The SIM2-151A also achieves the industry’s smallest size among the high-voltage motor driver ICs rated for 15 A. The product is available in the package with not only a decreased volume size but also the heat dissipation equivalent of the conventional package. It benefits to downsize the PCB, save cost as well as increase reliability.
