ИС переключателя электропитания – распределение электропитания MAX4785EXK+T

Переключатель силовой нагрузки , ограничение тока, 1 выход, 2.3В - 5.5В, 120мА/0.7Ом выход, SC-70-5

The MAX4785EXK+T is a 50mA current limit switch in 5 pin SC-70 package. This switch features an internal current limiting to prevent host device from being damaged due to faulty load conditions, analogue switch has a low 0.7ohm on-resistance and operate from a 2.3V to 5.5V input voltage range. When the switch is on and a load is connected to the port, blanking time of 14ms ensures that the transient voltages settle down. If after this blanking time load current is greater than the current limit, the MAX4785 enter a latch-off state where the switch is turned off and FLAG (complementary) is issued to the microprocessor. The switch can be turned on again by cycling power or the ON pin. The current limits makes device ideal for load-switching applications, it is also used at PDAs and palmtop devices, cell phones and GPS systems.
