Abstract
A shut down circuit is provided to guarantee an integrated circuit to be wholly shut off when a user pushes a button to order the shut off. As composed with the prior art, the shut down circuit has been provided with a latch circuit placed between the integrated circuit and a power management unit. The latch circuit includes two switching circuits arranged to clamp each other when a shut off order is presented. The switching circuits clamps each other to a conduction state, thus to generate shut off signals continually until the power management unit cut off the power supplied to the integrated circuit.
