| General Description |
|
The MIC94305 is an integrated load switch that incorporates Micrel’s Ripple Blocker™ active filter technology. The MIC94305 provides high-frequency ripple attenuation (switching noise rejection) for applications where switching noise cannot be tolerated by sensitive downstream circuits, such as RF applications. A low-voltage logic enable pin disconnects the pass element and puts the MIC94305 in a low current-shutdown state when disabled.
The MIC94305 operates from an input voltage of 1.8V to 3.6V, allowing true load switching of low-voltage power rails in any electronic device. The output voltage (VOUT) is set at a fixed drop (typically 170mV) from the input voltage (VOUT = VIN – 170mV). This maintains high efficiency independent of given load conditions and currents.
The MIC94305 is packaged in a 6-ball 0.84mm x 1.32mm CSP package, or 6-pin 1.6mm x 1.6mm Thin DFN package, and has a junction operating temperature range of -40°C to +125°C.
