Slew Rate Controlled Load Switch

Manufacturer's part number :


Manufacturer Skyworks


Description :

The AAT4250 SmartSwitch is a member of AnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family. It is a slew rate controlled P-channel MOSFET power switch designed for high-side load switching applications. This switch operates with an input voltage range from 1.8V to 5.5V, making it ideal for 2.5V, 3.3V, or 5V systems. The part features 1.5ms turn-on and 10μs turn-off time. The AAT4250 has an under-voltage lockout which turns off the switch when an under-voltage condition exists. Input logic levels are TTL compatible. The quiescent supply current is very low, typically 2μA. In shutdown mode, the supply current is typically reduced to 0.1μA or less. The AAT4250 is available in a Pb-free, 5-pin SOT23 (SOT25) package or a Pb-free, 8-pin SC70JW package and is specified over the -40°C to +85°C temperature range.
