MIC2095/MIC2097/MIC2098/MIC2099
Current-Limiting Power Distribution Switches General Description Features The MIC2095/97/98/99 family of switches are selfcontained, 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 noiseinduced, 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 undervoltage, 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 MLFВ® (TMLF) package.
