Pin Name

Description

1, 4

CTL (A/B) Control (Input): TTL-compatible control input. MIC2505,

MIC2505-1, and MIC2506 are active-high. MIC2505-2 is active-low.

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.

MIC2505-1 and -2 do not support open-load detect.

GND

Ground: Return.

—

GATE

Output MOSFET Gate: Open for fastest rise time. Connect

capacitor to ground to slow rise time. (See Figure 2-13)

5, 7

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

circuitry. Connect to supply.

MIC2505 series only: Pins 5 and 7 must be externally connected

together.

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.

MIC2505 series only: Pins 6 and 8 must be externally connected

together.
