Infineon: Arduino Shields for RGB lighting applications and motor controllers

The Infineon RGB LED Lighting Shield for Arduino is equipped with the microcontroller XMC1202 that has a Brightness Color Control Unit (BCCU) for the LED lighting control. The Shield for high current DC motor controllers for Arduino uses the high current half-bridge driver NovalithIC BTN8982TA.

Looking electronic part as FM600TU-07A FRS300BA50, http://www.modulesdirect.com is a independent distributor for hard to find electronic parts and obsolete components, get quote for more than 500 thousands par from our web will be responsed in 24 work hours, also the electronic components cann't find at our web, our saleman will find it and send the price for the parts which you want buy to you.

The RGB LED Lighting Shield with XMC1202

The module for RGB LED lighting enables the control of different LED light sources. It has three independent output channels for flicker control of multi-colored LEDs. The Shield is based on the microcontrollers XMC1202 from the XMC1200 series. This series provides, inter alia, the complete dimming control and flicker-free light over all Dimmungsstufen. Expand the shield can be a DMX communication interface for integration with lighting and audio systems. Also possible is the combination with a 24 GHz radar sensor, for example for motion detection.

DC Motor Control Shield with BTN8982TA

This Shield is half-bridge and full-bridge designs can be evaluated. It can drive two DC motors unidirectional or bidirectional DC motor. Fitted is the shield with two fully integrated high current half-bridge drivers for motor control of the type NovalithIC BTN8982TA. This combines three integrated circuits in a single package: two power ICs (a P-channel high-side MOSFET and an N-channel low-side MOSFET) and an integrated driver IC with a logic circuit for the power control and their monitoring. Other features include diagnostic functions such as current measurement, adjustability of the slew rate, dead-time generation and protection functions at overtemperature, undervoltage, overcurrent and short circuit.

The Novalith IC BTN8982TA is ideal for secure high-current PWM motor drives, which should be as small as possible and supports high-frequency pulse width modulation, for example, up to 30 kHz. Brushed DC motors can be operated up to 250 W continuous power (eg 12 V / 20 A). The current limitation of BTN8982TA can peak currents up to 55 A.

Until the end of January 2015, the two Shields Farnell Newark element14 and element14 are to relate. Then the two Arduino Shields will also be available by Infineon and its distributors.
