The MAX1823AEUB+ is a dual USB switch with fault blanking and autoreset in 10 pin μMAX package. The autoreset feature latches the switch off if output is shorted, saving system power. The switch reactivates when short circuit is removed. Each channel has supply current of 720mA and meet USB specifications. Low quiescent supply current (50μA) and standby current (3μA) conserve battery power in portable applications. It has multiple safety features to ensure that the USB port is protected. Built-in thermal overload protection limits power dissipation and junction temperature. Accurate internal current-limiting circuitry protects the input supply against both overload and short-circuit conditions. It is used in USB ports and hubs, notebook and desktop computers, PDAs and palmtop computers and docking stations.
Supply voltage range is 4V to 5.5V
Operating temperature range from -40°C to 85°C
Autoreset feature saves power
Built-in 20ms fault blanking, compliant to USB specification
