Infineon targets RGB lighting and motor control for Arduino

Infineon Technologies has unleashed two Arduino Uno R3-compatible shields geared for RGB lighting and motor control. The Infineon RGB LED Lighting Shield features the XMC1202 microcontroller with its Brightness Colour Control Unit (BCCU) for LED lighting control. The high-current DC Motor Control Shield contains the Infineon NovalithIC BTN8982TA, an integrated half-bridge driver for motor control.

The shields can be combined with the XMC1100 Boot Kit, which is equipped with a 32bit microcontroller of the XMC1000family. All XMC1000 products use the ARM Cortex-M0 processor.

The RGB LED Lighting Shield is an evaluation board for Arduino. It allows the adoption of different LED light engines to ensure fast prototyping and inexpensive evaluation. The RGB LED Lighting Shield offers three independent output channels for control of multi-colour LEDs. It is powered by the XMC1202 microcontroller of the XMC1200 series. The series provides all essentials for high-quality colour, such as full dimming control and flicker-free light at all dimming levels with low energy consumption. According to the company, the BCCU automated hardware engine provides a cost-sensitive and high-quality LED lighting solution. It is easy to configure and ensures smooth dimming and colour mixing. The shield can be expanded using a DMX interface for lighting and audio nodes or a 24GHz radar sensor for motion detection.

RGB LED Shield

The DC Motor Control Shield with BTN8982TA for Arduino enables prototyping of DC motor control designs with testing of half-bridge and full-bridge motor control applications. The Motor Control Shield is capable of driving two unidirectional DC motors or one bidirectional DC motor. It implements two NovalithIC BTN8982TA fully integrated high-current half-bridge drivers optimised for motor drive applications. The NovalithIC BTN8982TA combines three ICs in one package: two power chips (one p-channel high-side MOSFET and one n-channel low-side MOSFET) and an integrated driver IC with one logic circuit to control and monitor the power. Further feature highlights are diagnosis with current sense, slew rate adjustment, dead time generation and protection against over temperature, under-voltage, over-current and short circuit. Interfacing to a microcontroller is made easy as the NovalithIC BTN8982TA features logic level inputs.

DC Motor Control Shield

The NovalithIC BTN8982TA provides a solution for protected high-current PWM motor drives with very low board space. The Motor Control Shield is capable of handling high-frequency PWM of 30kHz.The shield supports brushed DC motor control up to 250W continuous load (i.e. at 12V / 20A) while the BTN8982TA is having a current limitation, which allows peak-currents up to 55A.

Both shields are available until end of January 2015, from Farnell element14 and Newark element14, afterwards also from Infineon and its distributors.
