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