Sub-GHz RF modules add out-of-the-box wireless connectivity

The SP1ML-868 (868 MHz SRD band) and SP1ML-915 (915 MHz ISM band) are ultra-low-power RF transceiver modules based on ST’s SPIRIT1 radio combining into a small form factor (10 x 14 mm) an antenna and crystal as well as an STM32L151RB microcontroller for application firmware. They come with the firmware for serial cable replacement and AT commands for RF and data configuration through the UART interface and include a Serial Wire Debug (SWD) interface. SP1ML modules are an out-of-the-box solution to add wireless connectivity to a range of connected objects, dramatically reducing time to market as they are already FCC and CE approved. More

Explore ST’s new vacuum cleaner motor speed control evaluation board

The STEVAL-IHM029V2 low-cost universal motor control evaluation board targets vacuum cleaners whose input power will be limited to 900 W in compliance with the 2009/125/EC directive starting in September 2017. The board controls the universal motor speed by an STM8S103 microcontroller which varies the motor conduction phase angle thanks to the T1235T-8T, a high-performance 12 A 800 V T-series Triac. This low-cost universal motor control demonstration board can also be used for motor speed control in food processors and power tools. More

 

New signal Schottky diode in 0201 package for mobile applications

Housed in the 0.3 mm thick 0201 chip-scale package, ST’s BAT30F4 is especially suited for mobile and consumer applications where space is a constraint. Occupying a PCB area of less than 0.2 mm², the BAT30F4 is rated at a VRRM of 30 V with a current rating of 300 mA. Its low forward voltage, leakage current and junction capacitance provide designers with an increased efficiency and power density solution and make it ideal for use as a reverse polarity protection or step-up DC-DC converter in mobile applications. Furthermore, it has the advantage of being RoHS compliant without exemption. More

Decompensated high-precision, rail-to-rail, low-power op amps for improved performance

The TSX7191 offers low power consumption and exhibits an offset voltage less than 200 µV. Its rail-to-rail input and output functions, associated with an extended power supply range from 2.7 V to 16 V, allows the TSX7191 to be used in a wide range of applications. The TSX7191 perfectly fits automotive requirements: -40 to 125 °C temperature range and ability to sustain 4 kV ESD. TSX7191 is the decompensated version of the unity-gain stable TSX711. Available in a tiny SOT-23 package, its stability and outstanding GBW of 8.5 MHz are guaranteed for gains greater than 10. More
