Arduino shields for RGB lighting and motor control from Infineon

New Products |
Infineon Technologies has added two shields for Arduino designs; both are compatible to Arduino Uno R3 and can be combined with the XMC1100 Boot Kit which is equipped with a 32-bit microcontroller from the XMC1000family.

All XMC1000 products use the ARM Cortex-M0 processor. The Infineon RGB LED Lighting Shield for Arduino hosts the XMC1202 microcontroller with its Brightness Colour Control Unit (BCCU) for LED lighting control. The high-current DC Motor Control Shield for Arduino contains the Infineon NovalithIC BTN8982TA, an integrated half-bridge driver for motor control.

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

The DC Motor Control Shield with BTN8982TA for Arduino enables fast and cost-effective prototyping of DC motor control designs with easy testing of half-bridge and full-bridge motor control applications. The Motor Control Shield is capable of driving two uni-directional DC motors or one bi-directional DC motor. The Shield implements two NovalithIC BTN8982TA fully integrated high-current half-bridge drivers for motor drives. The 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 features are diagnosis with current sense, slew rate adjustment, dead time generation and protection against over temperature, undervoltage, overcurrent and short-circuit. Interfacing to a microcontroller is enabled as the NovalithIC BTN8982TA has logic level inputs.

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

Until the end of January 2015, both Shields are available for purchase from Farnell element14; thereafter, direct from Infineon and its distributor network.
