1.1v至5.5V的摆率控制的负荷开关SiP32401A, SiP32402A

　　DESCRIPTION SiP32401A and SiP32402A are slew rate controlled load switches designed for 1.1 V to 5.5 V operation. 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 low voltage control logic interface （On/Off interface） that can interface with low voltage control signal without extra level shifting circuit. SiP32402A also integrates an output discharge switch that enables fast shutdown load discharge. Both SiP32401A and SiP32402A have exceptionally low shutdown current and provide reverse blocking to prevent high current flowing into the power source. SiP32401A and SiP32402A are in TDFN4 package of 1.2 mm by 1.6 mm.
