Abstract
An electronic device includes a motion sensitive power switching integrated circuit, which, in turn, includes a power switch connected between an input and an output, and a MEMS inertial sensing switch movable from a first position to a second position based upon motion thereof. The motion sensitive power switching integrated circuit also includes a detector operating the power switch to supply power to the output from the input based upon the MEMS inertial sensing switch moving from the first position to the second position. The first and second positions may be, respectively, a normally open position and a closed position. The device may be unpowered until the MEMS inertial sensing switch moves from the open to the closed position. The detector may generate a power on reset (POR) signal based upon the MEMS inertial sensing switch moving from the open to the closed position.
