SPI serial input (SI) bit overrides the parallel ON state control from IN1 to IN4
Vref is the threshold reference level for detecting an Open Load/Overload
The standard way of obtaining diagnostic information is as follows:
Clock in serial information into SI pin and wait approximately 200 μs to allow the outputs to
settle. Clock in the identical serial information once again - during this process the data com-
ing out at SO contains the bit combinations representing the diagnosis conditions as described
in figure 1.
Based on the needs of the application, a software routine should be programmed into the mi-
cro controller to set the corrective action of each fault condition.
Open Load Program Pin (OL/PRG)
To detect open load/short to ground each channel has an internal pull down source (300 μA
typ.) which pulls the drain voltage under the detection threshold in case of an open load or
short to ground condition.
If the TLE 6236 G is used to drive LEDs this pull down current could causes a slight glowing of
the LED. To avoid this, the device is provided with a program pin, which enables or disables
this open load detection. The OL/PRG pin is internally pulled up, i.e. the open load detection is
enabled if the OL/PRG pin is not connected. To disable the open load detection this pin must
be pulled to GND, e.g with a micro controller port.
In this way the open load detection can be enabled (e.g during start up of the system or in a
diagnosis routine) and disabled (e.g. during normal operation to avoid LED glowing) by the μC.
If the open load detection is disabled, the leakage current is reduced to a maximum of 1μA.
