Circuit Breaker Sense Input: This pin is the (-) Kelvin sense connection for the
output supply rail. A low-valued resistor (R

into the load. When the FB pin voltage is less than ≅0.8V, the voltage across the
sense resistor decreases linearly to a minimum of 12mV (typical) when the FB
pin voltage is at 0V.
To disable the circuit breaker (and defeat all current limit protections), the
SENSE pin and the VCC pin can be tied together.
Positive Supply Voltage Input: This pin is the (+) Kelvin sense connection for the
output supply rail. The nominal operating voltage range for the MIC2586 and the
MIC2586R is +10V to +80V, and VCC can withstand input transients up to
+100V.
