47 m

, 1.2 V to 5.5 V,

Low Quiescent Current Load Switch in Ultra Thin μDFN-4

DESCRIPTION

The SiP32475 is a compact, ultra thin high side load switch

that operates over a input voltage range from 1.2 V to 5.5 V.

Designed with a p-channel MOSFET featuring an adaptive

charge pump gate drive, the SiP32475 provides 47 m



switch on-resistance over a wide input voltage range and

maintains a low quiescent current level.

The SiP32475 also features slew rate control, reverse

blocking when the switch is off, and output discharge. With

guaranteed 1 V control logic high, the SiP32475 can

interface directly with a low voltage control I/O, without the

need for an extra level shift or driver. The device is logic high

enabled and a 2.8 M

 pulldown resistor is integrated at the

logic control EN pin. The slow slew rate of the SiP32475

limits the in-rush current and minimizes the switching noise.

The SiP32475 is available in the μDFN-4L 1 mm x 1 mm

package with a 0.3 mm thickness. The device is specified for

operation over a temperature range of -40 °C to +85 °C.
