Figure 2 Application example
The parameters of the PWM output are period and duty cycle. Both have to be configured during NFC configuration. The values of the configuration parameters have to be calculated according to the requirements of the application. Using an external R/C circuitry with a given time constant, the duty cycle and period of the PWM can be calculated to generate any value between minimum and maximum output voltage of the digital PWM output driver. The calculated parameters including the aging function are written into the NVM of the NLM0011/NLM0010 during NFC configuration. That can only be done if the NLM0011/NLM0010 is powered off. The NLM0011/ NLM0010 will harvest the energy from the electromagnetic NFC field and supply itself in that case.
