For the MIC2583/83R, a capacitor connected to
CFILTER is used to set the timer which activates the
circuit breaker during overcurrent conditions. When the
voltage across the sense resistor exceeds the slow trip
current limit threshold of 50mV, the overcurrent timer
begins to charge for a time period (t
by C
and for the MIC2582, t
elapses, then the circuit breaker is activated and the
GATE output is immediately pulled to ground. For the
MIC2583/83R, the following equation is used to
determine the overcurrent timer period, t
where V
I
and 3 provide a quick reference for several timer
calculations using select standard value capacitors.
