FUNCTIONAL DESCRIPTION
The L9637 is a monolithic bus driver designed to
provide bidirectionalserial communicationin auto-
motive diagnostic applications according to the
specification”DiagnosticSystems ISO9141”.
The device provides a bidirectional link, called K,
to the V
Bat
related diagnosis bus. It also includes
a separate comparator L which is also able to be
linked to the V
Bat
bus. The input TX and output
RX of K are related to V
CC
with her integratedpull
up resistances. Also the L comparator output LO
has a pullup resistance connectedto V
CC
.
The maximum external pull up resistance at K re-
lated to V
S
should not be higher than R
KO
≤
5K
to achieveclear output ON conditions.
All V
Bat
bus defined inputs LI and K have supply
voltage dependent thresholds together with suf-
ficent hysteresis to suppress line spikes. These
pins are protected against overvoltages, shorts to
GND and V
S
and can also be driven beyond V
S
and GND. These features are also given for TX,
RX and LI only taking into account the behaviour
of the internal pull up resistances. The thermal
shut down function switches OFF the K output if
the chip temperatureincreases above the thermal
shut down threshold. To reactivate K again the
chip temperature must decrease below the K
switch ON temp. To achieveno fault forV
S
under-
voltage conditions the outputs will be switched
OFF and stay at high impedance. The device is
also protected against reverse battery condition.
During lack of V
S
or GND all pins shows high im-
pedance characteristic.To realize a lackof the V
S
related bus line LI and K the outputs LO and RX
showsdefined ON status.
