POWER SWITCHES WITH FLAG 80mΩ, 0.5A/0.8A/1A/1.5A HIGH-SIDE
DESCRIPTION
The A4772 is a low voltage, single N-MOSFET high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. The A4772 equipped with a charge pump circuitry to drive the internal MOSFET switch; the switch's low RDS(ON), 80mΩ, meets USB voltage drop requirements and a flag output is available to indicate fault conditions to the local USB controller. Additional Features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout...
