APPLICATION INFORMATION
Most integrated circuits, both HNMOS and bipolar,
are very sensitive to positive and negative overvol-
tages on the supply and at the inputs.
These transients occur in large numbers and with
different magnitudes in the automotive environment,
making adequate protection for devices ai-med at it
indispensible.
Overvoltages on the supply line are faced through
high voltage integration technologies or through ex-
ternal protection (transil, varistor).
Signal inputs are generally protected using clamp
diodes to the supply and ground, and a current limi-
ter resistor. However, such solutions do not always
completely satisfy the protection specifications in
terms of intervention speed, negative clamping and
current leakage high enough to change analog si-
gnals.
The L9700 device combines a high intervention
speed with a high precision positive and negative
clamp and a low current leakage providing the opti-
mal solution to the problems of the automotive en-
vironment.
The high intervention speed, due to the pre-bias of
the limiter stage and internal feedback, limits the
voltage overshoot and avoid the use of external ca-
pacitors for the limitation of the transient rise times.
Figure 3 illustrates a typical automotive application
scheme. The resistor RS limits the input current of
the device and is therefore dimensioned considering
the characteristics of the transients to be eliminated.
Consequently :
Vtransient Peak
RS =
IIN MAX
The CIN capacitors must be used only on analog in-
puts because they present a low impedance during
the sampling period.
