4.2.1 PWM/DO/DI_Type005
Output (PWM/DO)
• This kind of pin is a current sourcing output with a pull-up selection
• In other words, the pin connects the load to a positive supply voltage
• When the pull-up is selected, it will affect two output pins (the pairs are indicated with upper
case characters in the pin table's Group column in section
Pinout Map).
• This pull-up feature is for open load detection when pin is used as an output.
• 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.
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.
• This pin can be used also with NPN-type sensors – sensors with open collector/open drain.
