Pin Symbol Function
1 OUT
Output to the load. The pins
1 and 5 must be shorted with each other
especially in high current applications!
3)
2 IN Input, activates the power switch in case of short to ground
3 V
bb
Positive power supply voltage, the tab is electrically connected to this pin.
In high current applications the tab should be used for the V
bb
connection
instead of this pin
4)
.
4 IS
Diagnostic feedback providing a sense current proportional to the load
current; zero current on failure (see Truth Table on page 7)
5 OUT
Output to the load. The pins
1 and 5 must be shorted with each other
especially in high current applications!
3)
Maximum Ratings at Tj = 25 °C unless otherwise specified

3)
Not shorting all outputs will considerably increase the on-state resistance, reduce the peak current capability
and decrease the current sense accuracy
4)
Otherwise add up to 0.5 mΩ (depending on used length of the pin) to the R

tab.
