Microchip Technology

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 MIC2101/02 are constant-frequency, synchronous buck controllers featuring a unique adaptive ON-time control architecture. The MIC2101/02 operates over an input supply range from 4.5V to 38V and can be used to supply up to 15A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%. The device operates with programmable switching frequency from 200kHz to 600kHz. Hyper Light Load™ architecture provides the same high-efficiency and ultra-fast transient response as the Hyper Speed Control architecture under the medium to heavy loads, but also maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous-mode operation. The MIC2101/02 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include under voltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, fold-back current limit, "hiccup" mode short circuit protection and thermal shutdown.
