NLM0011/NLM0010- LED Driver IC with effective NFC-PWM programming

NLM0011/NLM0010- LED Driver IC with effective NFC-PWM programming

Infineon Technologies developed the NFC-PWM series (NLM0011 & NLM0010) for fast and cost effective implementation of NFC programming for LED drivers. The NFC programming can replace the labor intensive “plug-in resistor” current setting method with the contact less NFC interface. It improves the operational efficiency and flexibility in value chain by implementing automatic programming in the manufacturing line. With this it reduces the LED driver variants, simplifies the selection of LED modules, and allows end-of-line configuration.

The devices are NFC wireless configuration ICs with configurable PWM output primarily designed for LED applications. It enables cost effective NFC programming implementation by using a PWM signal directly to control the analog driver IC which eventually reduces the cost of BOM.

These devices can operate in two different modes,  Active and Passive Mode. When the device is in passive mode the LED driver is not powered and the configurations of PWM parameters can be done via the NFC interface. When the device is in Active mode, it is powered by a Vcc Voltage supply, and a PWM output is generated according to the stored parameters. The PWM signal is converted into a desired DC voltage to control the current output of an LED driver by using an external R/C filter.


  • Configurable pulse width modulation (PWM) output
  • NFC contactless interface compliant to ISO/IEC 18000-3 mode 1 (ISO/IEC 15963)
  • Constant light output (CLO) with 8 configurable points
  • Integrated operation-time counter (OTC) and on/off counter
  • Non-volatile memory (NVM) including UID and 20 bytes free memory for user data
  • Stable PWM output with fixed 2.8 V amplitude and +/-0.1% duty cycle accuracy

NLM0011 has the Integrated constant lumen output (CLO) function which compensated the luminous flux drop (aging effect) of the LED module by automatically adjusting the LED current to the aging characteristics of the LEDs. NLM0011 automatically adjusts the PWM duty cycle to compensate the LED degradation with the help of integrated operation time counter (OTC) and stored LED degradation curve in the CLO table.

There is no need for firmware development efforts as the device can fit perfectly to the mainstream analog driver ICs and can easily adapt into the existing designs to replace the “Plug-in- resistor” current configuration concept. The solution can easily go along with the existing analog LED driver designs and the NFC programming specification form the module –Driver interface special interest Group (MD-SIG). The NFC-PWM series can also be used in applications such as motor control and SMPS. The NLM0011 and NLM0010 can be ordered now in a SOT23-5 package, for more information you can use the datasheet or product page from Infineon.
