PROTECTING
REVERSEBATTERY
The simplest way to protect the device against a
continuous reverse battery voltage (-26V) is to
insert a Schottkydiode between pin 1 (GND) and
ground, as shown in the typical application circuit
(fig. 3).
THE
DEVICE
AGAINST
The consequences of the voltage drop across
this diodeare as 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 V
STAT
are increased by V
F
with
respectto power GND).
The undervoltageshutdown 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
IH
, V
IL
and V
STAT
takes
place and no negative voltage appears on the
INPUT pin; this solution allows the use of a
standarddiode, with a breakdown voltage able to
handle any ISO normalized negative pulses that
occours in the automotiveenvironment.
