1.1V至5.5V擺率控制的負(fù)荷開關(guān)在tsot23-6,SiP32508, SiP32509

　　DESCRIPTION The SiP32508 and SiP32509 are a slew rate controlled load switches designed for 1.1 V to 5.5 V operation. The switch element is of n-channel device that provides low Ron of 44 m? typically over a wide range of input. The devices guarantee low switch on-resistance at 1.2 V input. They feature a controlled soft-on slew rate of typical 2.5 ms that limits the inrush current for designs of heavy capacitive load and minimizes the resulting voltage droop at the power rails. These devices feature a low voltage control logic interface （On/Off interface） that can interface with low voltage control signals without extra level shifting circuit. SiP32508 and SiP32509 have exceptionally low shutdown current and provides reverse blocking to prevent high current flowing into the power source. SiP32509 integrates a switch OFF output discharge circuit. Both SiP32508 and SiP32509 are available in TSOT23-6 package.
