Voltage Dividers

18SCT001 1500V Voltage Monitor with Low-Pass Filter

The 18SCT001 is a voltage divider typically used to sense system voltage from 0V up to 1500V. For example, it can be used to monitor voltage generated from an embedded charge-pump. The chip has a built-in low-pass filter allowing the chip to filter voltage changes typical of voltage pumping frequencies while allowing accurate voltage measurements when the pump is turned-off. The voltage divider ratio is mask programmable in a wide range from 1.0E-5 to 0.2000.
