Table 2: Absolute Maximum Ratings

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is

not implied.

Table 3: Thermal Data

(*) This value depends from thermal design of PCB on which the device is mounted.

Name and Function

1, 2

IN

Input P-Channel MOSFET source. Bypass IN with a 1

µF capacitor to ground.

3ON

Active Low Switch On Input. A logic low turns the switch ON

4

GND

Ground

5

SET

Set Current Limit Input. A resistor from SET to GROUND sets the current limit for

6, 7

OUT

Switch Output. P-Channel MOSFET drain. Bypass OUT with a 0.1µF capacitor to

GROUND.

8FAULT

Fault Indicator Output. This open drain output goes low when in current limit or

when the die temperature exceeds 135°C
