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.
FEATURES
• 1.1 V to 5.5 V operation voltage range
