MIC2095/MIC2097/MIC2098/MIC2099
Current-Limiting Power Distribution Switches
General Description
Features
The MIC2095/97/98/99 family of switches are self-
contained, current-limiting, high-side power switches, ideal
for power-control applications. These switches are useful
for general purpose power distribution applications such as
digital televisions (DTV), printers, set-top boxes (STB),
PCs, PDAs, and other peripheral devices.
The current limiting switches feature either a fixed
0.5A/0.9A or resistor programmable output current limit.
The family also has fault blanking to eliminate false noise-
induced, over current conditions. After an over-current
condition, these devices automatically restart if the enable
pin remains active. The MIC2097 switch offers a unique
new patented Kickstart feature, which allows momentary
high-current surges up to the secondary current limit
(ILIMIT_2nd). This is useful for charging loads with high inrush
currents, such as capacitors.
The MIC2095/97/98/99 family of switches provides under-
voltage, over-temperature shutdown, and output fault
status reporting. The family also provides either an active
low or active high, logic level enable pin.
The MIC2095/97/98/99 family is offered in a space saving
1.6mm x 1.6mm Thin MLF® (TMLF) package.

Pin Name Pin Function
VOUT Switch output (Output): The load being driven by the switch is connected to this pin.
NC No Connect; Pin not used.
ILIMIT
FAULT/
Current Limit (Input): A resistor from this pin to ground sets the current limit value. See
the “setting ILMIIT” section for details on setting the resistor value.
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.
ENABLE Switch Enable (Input): Logic high on this pin enables the switch.
ENABLE/ Switch Enable (Input): Logic low on this pin enables the switch.
GND
VIN
EP
Ground.
Power input (Input): This pin provides power to both the output power switch and the
internal control circuitry.
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.
