Pin Function
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
Current Limit Response Timer: A capacitor connected to this pin defines the
period of time (t

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
overcurrent condition or when an undervoltage lockout condition exists. The
/FAULT pin requires a pull-up resistor (10k minimum) to VCC.
Discharge Output: When the MIC2583/83R is turned off, a 500
resistor at this output allows the discharging of any load capacitance to ground.
No internal connection.
