NFC configuration IC with integrated CLO function and pulse width modulation (PWM) output NLM0011
Infineon’s dual-mode NFC configuration IC (NLM0011) with pulse width modulation (PWM) output is designed for LED applications to enable the emerging NFC programming feature, which is compatible with the Module-Driver Interface Special Interest Group (MD-SIG). In addition to the NFC-programming, advanced features such as constant lumen output (CLO) and on/off counting are integrated. Thanks to the dual mode NFC configuration IC’s features, customers can easily enable them without needing an additional microcontroller.
As the NLM0011 is a state-machine, no firmware development efforts are required. It can conveniently adapt to existing designs which enables replacement of the plug-in-resistor current configuration concept .
