Linear Tech has introduced a dual input power prioritiser for 1.8V to 18V systems which preserves rails during brown-outs and prompts graceful shut-down on power loss. Designed to work in battery, capacitor and adaptor-powered circuits, LTC4420 is monolithic and included two 500mA 2Ω rail-switching p-channel mosfets. Crucially, there is no requirement for the back-up supply voltage to be lower ...
