The A2526EL/M and A2536EL/M are integrated high-side dual power switches, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements. The A2526EL/EM ENABLE inputs are active high; the A2536EL/EM are active low.
