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

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

• 44 m

 typical from 1.5 V to 5 V

• Slew rate controlled turn-on: 2.5 ms at 3.6 V

• Low quiescent current < 1 μA when disabled

• Reverse current blocking when switch is off, with

guaranteed less than 2 μA leakage

• Material categorization: for definitions of compliance
