Current-Limited Switch for Two USB Ports
General Description
The MAX1930 current-limited 70m ? switch with built-in
fault blanking provides an accurate, preset 1.2A to 2.3A
current limit, making it ideal for dual USB applications.
Its low quiescent supply current (16μA) and standby
current (1μA) conserve battery power in portable appli-
cations. The MAX1930 operates with inputs from 2.7V to
5.5V, making it ideal for both 3V and 5V systems.
The MAX1930 has several safety features to ensure that
the USB port is protected. Built-in thermal-overload
protection limits power dissipation and junction tempera-
ture. The device also has accurate internal current-limiting
circuitry to protect the input supply against overload.
The MAX1930 is offered in a space-saving 8-pin SO
package and operates over the extended (-40°C to
+85°C) temperature range.
