1.1 V to 5.5 V, Slew Rate Controlled Load Switch

DESCRIPTION

SiP32408 and SiP32409 are slew rate controlled load

switches designed for 1.1 V to 5.5 V operation.



These 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.



SiP32408 and SiP32409 feature a low voltage control logic

interface (on/off interface) that can interface with low voltage

control signals without extra level shifting circuit.



Both SiP32408 and SiP32409 have exceptionally low

shutdown current and provide reverse blocking to prevent

high current flowing into the power source.



SiP32409 integrates a output discharge circuit for fast turn

off.



Both SiP32408 and SiP32409 are available in TDFN4

package of 1.2 mm by 1.6 mm.
