Function
O ^{Output to the load. The pins 1,2,6 and 7 must be shorted with each other}
especially in high current applications! ³⁾
O Output to the load. The pins 1,2,6 and 7 must be shorted with each other
especially in high current applications! ³⁾
I Input, activates the power switch in case of short to ground
+
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 pin⁴⁾.
S ^{Diagnostic feedback providing a sense current proportional to the load}
current; zero current on failure (see Truth Table on page 7)
O
Output to the load. The pins 1,2,6 and 7 must be shorted with each other

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 0.7 mΩ (depending on used length of the pin) to the RON if the pin is used instead of the}
tab.
5_{) RI = internal resistance of the load dump test pulse generator.}
6_{) VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839.}
