Pin Symbol Function
1 OUT O
Output to the load. The pin 1 and 5 must be shorted with each
other especially in high current applications!*)
2 IN I
Input, activates the power switch in case of short to ground
Tab/(3) V
bb
+
Positive power supply voltage, the tab is shorted to this pin.
4 IS S
Diagnostic feedback providing a sense current proportional to the load
current; high current on failure (see Truth Table on page 6)
5 OUT O
Output to the load. The pin 1 and 5 must be shorted with each
other especially in high current applications!*)
*) Not shorting all outputs will considerably increase the on-state resistance, reduce the peak current capability
and decrease the current sense accuracy
Maximum Ratings at Tj = 25 °C unless otherwise specified
