1 For a high side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load. This negative voltage
is clamped by the device.
2 The load current is self-limited during the response time for short circuit load protection. Response time is measured from when input goes
high.
3 If the load resistance is low, but not a complete short circuit, such that the on-state voltage remains less than V
BL(TO)
, the device remains in
current limiting until the overtemperature protection operates.
