OptiMOS™ 7 40 V motor-drives optimized power MOSFETs in a PQFN 3.3 x 3.3 package. The Ultimate Motor-Drives Solution. The OptiMOS™ 7 40 V motor-drives optimized offers up to 3x wider Safe Operating Area vs. OptiMOS™ 6, providing highest reliability. An increased threshold voltage of 3.2 V offers enhanced induced turn-on ruggedness. 70% lower transconductance enables ease of use by improving current sharing, reducing voltage overshoot and an inherent short circuit current limitation characteristic boosting performance while handling harsh operation conditions.
