The evaluation tests propagation delay matching, CMTI (Common Mode Transient Immunity), and reliability under thermal stress for the COS2103 (600V Half-Bridge) and COS2101 (600V High/Low Side) gate drivers. Wafer processing utilizing silicon-on-insulator (SOI) technology isolates high-voltage wells, eliminating parasitic latch-up risks common in bulk silicon alternatives.
