For a high-side switch, the load pin voltage goes negative with respect to ground during the turn-off of an inductive load.
This is the current drawn from the supply when the input is LOW, and includes leakage current to the load.
Defined as in ISO 10483-1. For comparison purposes only.
The supply and input voltages for the R
BLon
tests are continuous. The specified pulse duration is t
p
= 300
μ
s, and refers only to the
applied load current.

35 V. A low current load can be detected in the on-state.
Undervoltage sensor causes the device to switch off and reset.
Overvoltage sensor causes the device to switch off to protect the load.

[11] The battery to load threshold voltage for short circuit is approximately proportional to the battery supply voltage.
[12] After cooling below the reset temperature the switch will resume normal operation.
[13] The status output is an open drain transistor and requires an external pull-up circuit to indicate a logic HIGH
