uS5651P - uPI Semiconductor

uS5651P ADC Prefilter

The uS5651P is an ADC prefilter with analog multiplexer, which output is used mainly by the analog to digital converter (ADC) of GPU/ASIC for voltage and current monitoring. This device has four input channels, and each channel has an independent voltage and current monitoring input. This part senses the voltage across the shunt resistor for current monitori.
