FUNCTIONAL DESCRIPTION
The device has a

The truth table shows input, diagnostic output
status and
output voltage
operation and fault conditions. The output signals
are processedby internal logic.
To protect the device against short circuit and
over current conditions, the thermal protection
turns the integratedPower MOS off ata minimum
junction temperature of 140

automatically turned on again. To ensure the
protection in all V

conditions and in all the
junction temperaturerange it is necessary to limit
the voltage drop across Drain and Source (pin 3
and 5) at 28V accordingto:

where:

Driving inductiveloads, an internal function of the
device ensures the fast demagnetization with
typical voltage (V

) of -18V.
This function allows the reduction of the power

Based on this formula it is possible to know the
value of inductance and/or current to avoid a
thermalshut-down.
PROTECTING THE DEVICE AGAINST RE-
VERSEBATTERY
The simpliest way to protect the device against a
continuous reverse battery voltage (-36V) is to
insert a Schottky diode between pin 1 (GND)and
ground, as shown in the typical application circuit
(Fig. 3). The consequences of the voltage drop
across this diode areas follows:
If the input is pulled to power GND, a negative
voltage of -V
f
is seen by the device. (V
il
, V
ih
thresholds and Vstat are increased by V
f
with
respectto power GND).
The undervoltageshut-down level is increased by
V
f
.
If there is no need for the control unit to handle
external analog signals referred to the power
GND, the best approach is to connect the
reference potential of the control unit to node [1]
(see application circuit in fig. 4), which becomes
the common signal GND for the whole control
board avoiding shift of V
ih
, V
il
and V
stat
. This
solutionallows the use of a standard diode.
