Notes
17.
Output-ON resistance as measured from output to V+ and ground.
18.
Active current limitation applies only for the low-side MOSFETs.
19.
Outputs switched OFF with D1 or D2.
20.
Fault Status output is an open Drain output requiring a pull-up resistor to 5.0 V.
21.
Fault Status Leakage Current is measured with Fault Status HIGH and not SET.
22.
Fault Status Set Voltage is measured with Fault Status LOW and SET with IFS = 300 A.
