... Open-load detection is active when the switch is off. When off, a normal load pulls the output pin low. If the load is open, an optional, external, high-value resistor pulls the output pin high, triggering the fault flag. MIC2505-1 and -2 versions are tailored to Universal Serial Bus (USB) applications and do not include open-load detection. ...

... April 2004 Pin Function Control (Input): TTL compatible control input. High input typically > 1.8V. Low input typically < 1.6V. MIC2505, MIC2505-1 and MIC2506 are active high. MIC2505-2 is active low. Fault Flag (Output): Active-low, open-drain output. If CTL is low, indicates open load. If CTL is high, indicates current limit, thermal shutdown, or UVLO ...

... CTL, thermal shutdown, or UVLO (undervoltage lockout). An optional, external capacitor may be connected to the MIC2505 GATE to lengthen the rise time. This slows the turn on of the MOSFET output switch. (See “MIC2505 Turn-On Delay” graph.) Since this pin connects directly to the MOSFET gate, use ESD precautions when contacting components connected to this pin ...

... GND Socket A gate capacitor may be added to the MIC2505 to slow the turn on time even more, reducing the inrush current. See “MIC2505 Turn-On Delay” graph. The UVLO feature insures that each time the card is removed and V of the output switch is discharged to zero volts. A controlled turn-on is executed each time a board is plugged in, even with multiple insertions ...
