PWRGD
Power-Good Output: Open drain N-channel device, Active High. When the
voltage at the FB pin is lower than 1.24V, PWRGD output is held low. When the
voltage at the FB pin exceeds 1.24V, then PWRGD is asserted immediately. The
PWRGD pin requires a pull-up resistor (10k& minimum) to VCC.

5
CFILTER
Current Limit Response Timer: A capacitor connected to this pin defines the
period of time (t
OCSLOW
) in which an over current event must last to signal a fault
condition and trip the circuit breaker. If no capacitor is connected, then t
OCSLOW
 
defaults to 5祍.
n/a
11
/FAULT
Circuit Breaker Fault Status Output: Open drain N-channel device, Active Low.
The /FAULT pin is asserted when the circuit breaker trips due to an over current
condition or when an under-voltage lockout condition exists. The/FAULT pin
requires a pull-up resistor (10k& minimum) to VCC.
n/a
13
DIS
Discharge Output: When the MIC2583/83R is turned off, a 500& internal resistor
at this output allows the discharging of any load capacitance to ground.
n/a
6, 9, 10
NC
No internal connection.
