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.
MIC2505-1 and -2 do not support open-load detect
Ground: Return.
Output MOSFET Gate: Open for fastest rise time. Connect capacitor to
ground to slow rise time. (See MIC2505 Turn-On Delay graph)
Supply Input: Output MOSFET drain. Also supplies IC’s internal circuitry.
Connect to supply.
MIC2505 series only:
Switch Output: Output MOSFET source. Typically connect to switched side
of load. Output voltage can be pulled above input voltage in off mode.
