The VN02NSP/VN02NPT are monolithic devices
made using SGS-THOMSON Vertical Intelligent
Power Technology, intended for driving resistive
or inductive loads with one side grounded.
Built-in thermal shut-down protects the chip from
over temperature and short circ uit.
The input control is 5V logic level compatible.

FUNCTIONAL DES CRI PT ION
The device has a diagnostic output which
indicates open circuit (no load) and over
temperature conditions. The output signals are
processed by internal logic.
To protect the device against short circuit and
over-current condition, the thermal protection
turns the integrated Power MO S off at a minimum
junction temperature of 140
temperature returns to about 125
o
C. When the
o
C the switch is
automatically turned on again.
In short circuit conditions the protection reacts
with virtually no delay, the sensor being located in
the region of the die where the heat is generated.
PROTECTING THE DEVICE AGAINST
REVERSE BATTERY
The simplest way to protect the device against a
continuous reverse battery voltage (-26V) 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 are as follows:
- If the input is pulled to power GND, a negative
voltage of -V
thresholds and V
respect to power GND).
The undervoltage shutdown 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 infig. 4), which becomes
the common signal GND for the whole control
board.
In this way no shift of V
place and no negative voltage appears on the
INPUT pin; this solution allows the use of a
standard diode, with a breakdown voltage able to
handle any ISO normalized negative pulses that
occours in the automotive environment.
