Pin Name

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 (10kΩ minimum) to VCC.

Current Limit Response Timer: A capacitor connected to this pin defines the

period of time (tOCSLOW) in which an over current event must last to signal a fault

condition and trip the circuit breaker. If no capacitor is connected, then tOCSLOW

defaults to 5µs.

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 (10kΩ minimum) to VCC.

Discharge Output: When the MIC2583/83R is turned off, a 500Ω internal resistor

at this output allows the discharging of any load capacitance to ground.

No internal connection.
