MIC94161/2/3/4/5
3A High-Side Load Switch
with Reverse Blocking General Description Features The MIC94161/2/3/4/5 is a family of high-side load
switches designed to operate from 1.7V to 5.5V input
voltage. The load switch pass element is an internal
14.5mΩ 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 Г— 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 the device is
turned OFF. Additionally, the MIC94161 features
overvoltage protection to protect the load when the input
voltage is above 4.55V, as well as a precise enable
threshold which keeps the MIC94161 in the default OFF
state until the EN pin rises above 1.15V.
The MIC94161/2/3/4/5 operating voltage range makes
them ideal for Lithium-ion and NiMH/NiCad/Alkaline
battery-powered systems, as well as non-battery-powered
applications. The devices provide low quiescent current
and low shutdown current to maximize battery life.
