Description
1
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
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.
3
6
GND Ground: Return.
4
—
GATE Output MOSFET Gate: Open for fastest rise time. Connect
capacitor to ground to slow rise time. (See Figure 2-13)
5, 7
7
IN
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.
