1.1 V to 5.5 V, Slew Rate Controlled Load Switch in TSOT23-6
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
R_on 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.
