Murata supplies the IMX-060 evaluation board to provide a ready-made hardware environment for testing its IRA-S series of pyroelectric infrared (PIR) sensors.
The IRA-S sensors are available in a leaded package. Murata also makes a range of five fresnel lenses, supplied separately. This evaluation board features an IRA-S210ST01 sensor with the IML-0685 and IML-0688 lenses.
The EVSPIN958 single brushed dc motor driver expansion board is an easy-to-use solution for testing the performance of the STSPIN958 5 A full-bridge driver from STMicroelectronics. It supports a voltage range from 5 V to 58 V with a phase current up to 5 A.
The XMC1400 series from Infineon enables design engineers to safely handle motor systems consuming up to hundreds of Watts. The debug interface is isolated from the XMC1400 microcontroller and the position detection interfaces to guarantee safe operation during software development.
The kit includes a power board connector, a set of position interface circuits with Hall sensor and encoder connectors, a USIC interface, and the isolated on-board debug interface.
Together with a three-phase inverter, the board demonstrates the capabilities of the XMC1402 MCU. The board includes six LEDs, two for power indication, one user LED, one encoder-enabled indicator LED, and two debug LEDs, and a potentiometer.
The EVL012LED is an LED driver board. The architecture is based on a two-stage approach: a front-end PFC pre-regulator and a downstream resonant half-bridge converter, using the new STNRG012 IC that integrates the controllers of both sections in a single device.
The main features of this design are high efficiency, low power consumption at no load without an auxiliary supply, good power factor with low harmonic content, and reduced component count.
The board also has a full set of protection features including output overload, short-circuit, and over-voltage, all of which can be easily defined as latched or auto-restart by changing a value in the non-volatile memory of the controller.
The RDK-866 reference design describes a non-isolated buck converter power supply with an input-line zero-crossing detection output signal. The nominal output is 5 V/500 mA across the input range of 90 V to 300 V ac.
The system is powered by the LinkSwitch-TNZ IC controller. The LinkSwitch-TNZ family of ICs combines power conversion with lossless generation of an ac zero-crossing signal used typically for system clock and timing functions. The device incorporates a 725 V power MOSFET, oscillator, a high-voltage switched current source for self-biasing, frequency jittering, fast (cycle-by-cycle) current limit, hysteretic thermal shutdown, and output and input overvoltage protection circuitry in a monolithic IC.
Designs using the highly integrated LinkSwitch-TNZ ICs are more flexible than discrete implementations, reducing component count by 40% or more. The key design goal is low cost, low audible noise and compact form factor for use in wireless and relay power supplies.
