Environmental performance
The Single-chip inverter IC integrates various devices and circuits that are
necessary for inverter control onto a single die. The inverter IC controls a motor
at various speeds. The variable speed control improves the efficiency of
motors. The inverter IC downsizes the control board of motors utilizing single
chip structure,which allows the control board mounting the inverter IC to be
embedded into a motor. The inverter IC, which is a lead-free Pb-free product
conforming to JEITA Phase 3A, is environmentally-friendly.
Product performance
The Single-chip inverter IC is an intelligent power IC, developed based on a
unique dielectric separation technology. Because it's possible to design a latchup-
free structure, various IC formations are possible, even if high-voltage,
large-current output circuits and logic circuits are mixed.Compared with
conventional discrete substrate-based hybrid ICs, downsizing can be effected.
