AAT4250 Slew Rate Controlled Load Switch

The AAT4250 SmartSwitch™ is a member of AATI'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 .

Features

1.5ms turn on and 10µs turn off time. The AAT4250 has an under voltage lock out 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 5-pin SOT23 and 8pin SC70JW specified over -40 to 85°C. Features
