MC33690
ISO 9141 PHYSICAL INTERFACE
This interface module is fully compatible with
the ISO 9141 norm describing the diagnosis line.
It includes one transmitter (pin K) and 2 receivers
(pins K and AM).
The input stages consist of high voltage CMOS
triggers. The thresholds are ratiometric to VSUP.
A ground referenced current source (2.5μA typ.)
pulls down the input when unconnected.
When a negative voltage is applied on the K or
AM lines, the input current is internally limited by
a 2k
resistor (typ.) in series with a diode.
A current limitation allows the transmitter to drive
any capacitive load and protects against short
circuit to the battery voltage. An overtemperature
protection shuts the driver down when the
junction temperature exceeds 150
°
C (typ). Once
shut down by the overtemperature protection,
the driver can be switched on again :
- if the junction temperature has decreased
below the threshold,
- and by applying an off/on command, coming
either from the demodulator in configurations A
and B or directly applied on the input Tx in
configuration C (see pin K status in table 1 page
9).
The electromagnetic emission is reduced thanks
to the voltage slew rate control (5V/μs typ.).
