... MIC2582/MIC2583 control from the processor or other signal controller to shut off the output of the MIC2582/83. R4 pulls the GATE and the ON pin is held low until the connectors are fully mated. Once the connectors fully mate, a logic LOW at the /ON_OFF signal turns Q2 off and allows the ON pin to pull up above its threshold and initiate a start-up cycle ...

... The current limit threshold voltage (i.e., the “trip point”) for the MIC2582/83 may be as low as 42mV, which would equate to a sense resistor value of 42mV/I LOAD(CONT) numbers through for the case where the value of the sense ...

... V GS (MAX) = 12V) MIC2582/MIC2583 is not hard to meet. In MIC2582/83 applications, the gate of the external MOSFET is driven up to approximately 19.5V by the internal output MOSFET (again, assuming 12V opera- tion). At the same time, if the output of the external MOSFET (its source) is suddenly subjected to a short, the gate-source voltage will go to (19.5V – ...

... ON PCB Layout Considerations Because of the low values of the sense resistors used with the MIC2582/83 controllers, special attention to the layout must be used in order for the device’s circuit breaker function to operate properly. Specifically, the use of a 4-wire Kelvin connection to accurately measure the voltage across R is highly recommended ...
