Configuration with ES5436.1 to Measure ECU Digital Output Signals
Digital outputs of ECUs are often configured as open emitter or open collector.
In a vehicle, such outputs are connected to small loads.
To measure such digital output signals of an ECU in a HiL setup, the ES5436.1
can be used as load simulation and the ES5321 for measurement.
A schematic diagram for the ECU, the ES5321.1 and the ES5436.1 is shown in
Fig. 3-1 on page 27.
The ES5436.1 has 48 current channels for currents in the range of 5 mA to 150
mA. These current channels can be combined with the 48 digital inputs of the
ES5321.1 or the ES5321.2.
Technical Data of the ES5436.1 Power Sources
Tab. 3-1
Technical data of the power sources
When connecting the ES5436.1, observe the following note:
CAUTION!
Before connecting the ES5436.1, read the ES5436.1 User’s Guide.
Output
Data
Output current
5 mA to 150 mA
Output voltage
Passive circuit
Accuracy
+/- 3 mA at 150 mA
Galvanic isolation
max. 60 V to ground potential (functional separa-
tion)
Overvoltage protection
60 V abs. max.
Note
In the idle state (non activated load channel, operation mode "disabled") the
power source’s idle state current is ~70
μ
A.
Note
If the external vVBAT < 6 V the power source doesn’t carry any current.
Note
The ES5436.1 use cases "Pull-Up“, "Pull-Down“ and "Bipolar“ ( "Bipolar" for H-
bridge configuration, see ES5436.1 User’s Guide) can be configured by soft-
ware.
For this reason, make sure that +VBAT and -VBAT are always connected.
