MAX1823AEUB+T, USB интерфейс, с устранением неисправностей, Двойной Коммутатор USB, 4 В, 5.5 В, MAX

The MAX1823AEUB+T from Maxim Integrated Products is a dual USB switch with fault blanking and autoreset in 10 pin µMAX package. This dual, current limited switch with autoreset specifically made for USB application. 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-circuits conditions. It is used in USB ports and hubs, notebook and desktop computers, PDAs and palmtop computers and docking stations.
