Pin Description

Pin Number

Pin Name

Pin Function

1

VOUT

Switch output (Output): The load being driven by the switch is connected to this pin.

2

(MIC2095/MIC2098)

NC

No Connect; Pin not used.

2

(MIC2097/MIC2099)

ILIMIT

Current Limit (Input): A resistor from this pin to ground sets the current limit value. See

3

FAULT/

Fault status (Output): A logic low on this pin indicates the switch is in current limiting, or

has been shut down by the thermal protection circuit. This is an open-drain output

allowing logical OR’ing of FAULT/ outputs from multiple devices.

4

(MIC2095-1/MIC2097-1/

MIC2098-1/MIC2099-1)

ENABLE

Switch Enable (Input): Logic high on this pin enables the switch.

4

(MIC2095-2/MIC2097-2/

MIC2098-2/MIC2099-2)

ENABLE/

Switch Enable (Input): Logic low on this pin enables the switch.

5

GND

Ground.

6

VIN

Power input (Input): This pin provides power to both the output power switch and the

internal control circuitry.

EP

EP

Used to remove heat from die. Connect to ground. Use multiple vias to the ground

plane to minimize thermal impedance. See Applications Section for additional

information.
