Micrel MIC9416x High-Side Load Switches
Micrel MIC9416x high-side load switches are designed to operate from 1.7V to 5.5V input voltage. The load switch pass element is an internal 14.5mO RDSON N-Channel MOSFET which enables the device to support up to 3A of continuous current. Additionally, the load switch supports 1.5V logic level control and shutdown features in a tiny 1.5mm × 1mm 6-ball WLCSP package. The MIC9416x provides reverse current protection when the device is disabled. The device will not allow the flow of current from the output to the input when it is turned off and provides low quiescent current and low shutdown current to maximize battery life. The Micrel MIC9416x features over voltage protection to protect the load when the input voltage is above 4.55V as well as a precise enable threshold which keeps it in the default off state until the EN pin rises above 1.15V. The MIC9416x operating voltage range makes them ideal for Lithium-ion and NiMH/NiCad/Alkaline battery-powered systems, as well as non-battery-powered applications.
