MAX4915AELT+T

The MAX4914B/MAX4915A/B/MAX4917A/B family of switch es feature internal current limiting to prevent damage to host devices due to faulty load conditions.
These analog switches have a low 0.2Ω on-resistance and operate from a 2.3V to 5.5V input voltage range.
They are available with guaranteed 100mA, 200mA, and 300mA current limits, making them ideal for SDIO and other load switching applications. When the switch is on and a load is connected to the port, a guaranteed blanking time of 14ms ensures that the transient voltages settle down. If after this blanking time the load current is greater than the current limit, the MAX4914B/MAX4915B/MAX4917B latchoff versions enter a latchoff state where the switch is turned off and FLAG is issued to the microprocessor.
The switch can be turned on again by cycling the power or the ON pin.
