5.11 THE JUNCTION FIELD-EFFECT TRANSISTOR (JFET)
global.oup.coma voltage v DS causes current to flow from the drain to the source. When a negative v GS is ... is small, the channel is almost of uniform width. The JFET is simply operating as a resistance whose value is controlled by v GS. If we keep increasing v GS in the negative direction, a value is reached at which the depletion region occupies the ...

A 6ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. The AP22804/AP22814 is available in a standard Green SOT25,
