1、 AAT4250 Slew Rate Controlled Load Switch in SOT-23 Advanced Analogic Technologies, Inc. 1250 Oakmead Pkwy, Suite 310, Sunnyvale, CA 94086 (408)524-9684 Fax (408)524-9689 4250.2000.11.0.92 General Description The AAT4250 SmartSwitch? is a member of AnalogicTechs Application Specific Power MOSFET? (A
2、SPM?) product family. It is a Slew Rate Controlled P-channel MOSFET power switch designed for high-side load-switching applications. This switch operates with input voltage ranging from 2.7V to 5.5V, making it ideal for both 3V and 5V systems. The part features 1.5ms turn on and 10s turn off time. T
3、he AAT4250 turns off the switch when an under- voltage condition exists. Input logic levels are TTL compatible. The quiescent supply current is a low 4A max. In shutdown mode, the supply current decreases to 1A max. The AAT4250 is available in a 5 pin SOT-23 specified over -40 to 85C. Features =2.7V
