MIC2095/MIC2097/MIC2098/MIC2099 Current-Limiting Power Distribution Switches General Description Features The MIC2095/97/98/99 family of switches are self- MIC2095: 0.5A fixed current limit contained, current-limiting, high-side power switches, ideal MIC2098: 0.9A fixed current limit for power-control applications. These switches are useful MIC2097/99: Resistor programmable current limit for general purpose power distribution applications such as 0.1A to 1.1A digital televisions (DTV), printers, set-top boxes (STB), PCs, PDAs, and other peripheral devices. MIC2097: Kickstart for high peak current loads The current limiting switches feature either a fixed Under voltage lock-out (UVLO) 0.5A/0.9A or resistor programmable output current limit. Soft start prevents large current inrush The family also has fault blanking to eliminate false noise- Automatic-on output after fault induced, over current conditions. After an over-current Thermal protection condition, these devices automatically restart if the enable pin remains active. The MIC2097 switch offers a unique Enable active high or active low new patented Kickstart feature, which allows momentary 170m typical on-resistance 5V high-current surges up to the secondary current limit 2.5V 5.5V operating range (I ). This is useful for charging loads with high inrush LIMIT 2nd Applications currents, such as capacitors. The MIC2095/97/98/99 family of switches provides under- Digital televisions (DTV) voltage, over-temperature shutdown, and output fault Set top boxes status reporting. The family also provides either an active PDAs low or active high, logic level enable pin. Printers The MIC2095/97/98/99 family is offered in a space saving USB / IEEE 1394 power distribution 1.6mm x 1.6mm Thin MLF (TMLF) package.
