A diagnostic status ensures faster fault detection.
Active current limit is combined with a soft latched short circuit protection feature in
order to protect the device in the event of a short circuit.
Thermal shutdown for high temperature conditions has an automatic restart at a
lower temperature so providing protection against excessive power dissipation.
Active clamping protects the device against low energy spikes.
Undervoltage lockout means the device shuts down for low battery voltages, thus
avoiding faulty operation.
Overvoltage shutdown in the on-state protects a load such as a lamp filament from
potentially destructive voltage spikes.

[1] For a high-side switch, the load pin voltage goes negative with respect to the ground during the turn-off of an inductive load. This
negative voltage is clamped by the device.

[10] Overtemperature protection is not active during reverse current operation.
[11] Undervoltage sensor causes each output channel to switch off and reset.
[12] Overvoltage sensor causes each output channel to switch off to protect the load.
[13] After cooling below the reset temperature the channel will resume normal operation.
[14] The status output is an open drain transistor and requires an external pull-up resistor, RS, to indicate a logic HIGH.

Short-form specification — The data in a short-form specification is
extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with
the Absolute Maximum Rating System (IEC 60134). Stress above one or
more of the limiting values may cause permanent damage to the device.
These are stress ratings only and operation of the device at these or at any
other conditions above those given in the Characteristics sections of the
specification is not implied. Exposure to limiting values for extended periods
may affect device reliability.
