1

1 / 4

CTL (A/B)

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.

2

2 / 3

FLG (A/B)

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.

GND

Ground: Return.

GATE

Output MOSFET Gate: Open for fastest rise time. Connect capacitor to

ground to slow rise time. (See MIC2505 Turn-On Delay graph)

5, 7

7

IN

Supply Input: Output MOSFET drain. Also supplies IC’s internal circuitry.

Connect to supply.

6, 8

8 / 5

OUT (A/B)

Switch Output: Output MOSFET source. Typically connect to switched side

of load. Output voltage can be pulled above input voltage in off mode.
