Abstract :
This paper presents a leakage reduced HVIC using coarse-fine UVLO deploying a coarse UVLO to minimize current consumption of the fine UVLO in idling mode, which overcomes the disadvantage of conventional high side UVLO in HVIC. The proposed HVIC is implemented in 0.5μm Fairchild HDG4D 650V CMOS process. The total current consumption of HVIC including coarse-fine UVLO at 3V power supply is 1μA, which is 10 times smaller current consumption than HVIC with conventional high side UVLO.
