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.
