19-2254; Rev 3; 4/09 1A Current-Limited Switch for 2 USB Ports General Description The MAX1922 current-limited 70mΩ switch with built-in fault blanking provides an accurate, preset 1.
4A to 2.
1A current limit, making it ideal for dual USB applications.
Its low quiescent supply current (16µA) and standby current (1µA) conserve battery power in portable applications.
The MAX1922 operates with inputs from 2.
7V to 5.
5V, making it ideal for both 3V and 5V systems.
An overcurrent signal (OC) notifies the microprocessor that the internal current limit has been reached.
A 10ms overcurrent-blanking feature allows momentary faults (such as those caused when hot-swapping into a capacitive load) to be i...
