OVERTEMPERATURE PROTECTION (OVT)
If the chip temperature exceeds
Θlim (measured in
a central position in the chip) the chip deactivates
itself.
The following actions are taken:
• all the output stages are switched off;
• the signal DIAG is activated (active low).
Normal operation is resumed as soon as (typically
after some seconds) the chip temperature moni-
tored goes back below
ΘlimH.
The different thresholds with hysteretic behavior
assure that no intermittent conditions can be gen-
erated.
UNDERVOLTAGE PROTECTION (UV)
The supply voltage is expected to range from
9.5V to 35V, even if its reference value is consid-
ered to be 24V.
In this range the device operates correctly.
Below 9.5V the overall system has to be consid-
ered not reliable.
Consequently the supply voltage is monitored
continuously and a signal, called UV, is internally
generated and used.
The signal is “on” as long as the supply voltage
does not reach the upper internal threshold of the
Vs comparator Vsth. The UV
signal disappears
above Vsth.
Once the UV signal has been removed, the sup-
ply voltage must decrease below the lower
threshold (i.e. Vsth-Vshys) before it is turned on
again.
The hysteresis Vshys is provided to prevent inter-
mittent operation of the device at low supply volt-
ages that may have a superimposed ripple
around the average value.
The UV signal switches off the outputs, but has
no effect on the creation of the reference voltages
for the internal comparators, nor on the continu-
ous operation of the charge-pump circuits.
DIAGNOSTIC LOGIC
The situations that are monitored and signalled
with the DIAG output pin are:
• current limit (OVC) in action; there are 4 indi-
vidual current limiting circuits, one per each
output; they limit the current that can be sunk
from each output, to a typical value of
800mA, equal for all of them;
• under voltage (UV);
• over temperature protection (OVT).
The diagnostic signal is transmitted via an open
drain output (for ease of wired-or connection of
several such signals) and a low level represents
the presence of at least one of the monitored con-
ditions, mentioned above.
SHORT CIRCUIT OPERATION
In order to allow normal operation of the other in-
puts when one channel is in short cirtuit, an inno-
vative non dissipative over current protection (pat-
ent pending) is implemented in the device.
