4.2.3 PWM/DO/DI/CM_Type007
Output (PWM or DO)
• This type of pin is a current sourcing output with a current measurement feature (the pin
connects the load to a positive supply voltage through the shunt resistors).
• These outputs have a switching element called a smart FET. It has integrated features to
protect itself but also the external pin, wiring and actuator.
• These outputs are capable to generate pulse width modulated (PWM) output signals.
• When used as an output, the input feature indicates the output FET's state
Before the supply voltage can be connected to an output pin, the related power
switch must be switched on as well.
The FET outputs are grouped into pairs:
• The maximum continuous current for single output in the pair is 2,5 A.
• The maximum continuous current for the pair is 4 A.
The pairs are indicated with upper case characters in the pin table's Group column
in section Pinout Map
Input (DI)
• This pin can be used as a digital input (DI)
• A pin of this type can also be used as an input by using the output state monitoring feature.
• In those cases the output functionality of the pin must be kept in off state.
• It must be taken care in system design that the output unintentionally switching to on state
causes no harm to the system.
Current measurement
• When the pin is used as an output, the application can control the current with the
current measurement feature
• The firmware limits the maximum current to 2,5 A (when the current exceeds the value
more than 200 ms, the output is switched off)
