    28mΩ RDSON 3A High Side Load Switch
    in 1.2mm x 1.2mm MLFВ® Package General Description Features The MIC94044 and MIC94045 are high-side load switches
    designed to operate from 1.7V to 5.5V input voltage. The
    load switch pass element is an internal 28mΩ RDSON
    P-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 1.2mm x 1.2mm 4 pin MLFВ® package.
    The MIC94044/5 provides a slew rate controlled soft-start
    turn-on of 1ms (typical) to prevent an in-rush current event
    from pulling down the input supply voltage.
    The MIC94045 features an active load discharge circuit
    which switches in a 200Ω load when the switch is disabled
    to automatically discharge a capacitive load.
    Internal level shift circuitry allows low voltage logic signals
    to switch higher supply voltages. The enable voltage can
    be as high as 5.5V and is not limited by the input voltage.
    The MIC94044/5 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. ...
