STMicroelectronics

The LED driver board is based on a flyback topology using the STMicroelectronics®HVLED815PF device. The HVLED815PF device is a high-voltage primary switcher intended for operating directly from the rectified mains with minimum external parts and enabling high power factor (> 0.95) to provide an efficient, compact and cost effective solution for LED driving. It combines a high-performance low voltage PWM controller chip and an 800 V, avalanche rugged Power MOSFET, in the same package. There is no need for the optocoupler thanks to the patented primary sensing regulation (PSR) technique. The device assures protection against LED string fault (open or short).

The I3G4250D is a low-power 3-axis angular rate sensor able to provide unprecedented stability at zero-rate level and sensitivity over temperature and time. It includes a sensing element and an IC interface capable of providing the measured angular rate to the application through a standard SPI digital interface. An I²C compatible interface is also available. The sensing element is manufactured using a dedicated micromachining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers. The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit that is trimmed to better match the characteristics of the sensing element. The device has a selectable full scale (±245/±500/±2000 dps) and is capable of measuring rates with a user-selectable bandwidth. The I3G4250D is available in a plastic, land grid array (LGA) package and operates within a temperature range of -40°C to +85°C.

The IIS2DH is an ultra-low-power high-performance three-axis linear accelerometer with digital I2C/SPI serial interface standard output. The IIS2DH has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz. The device may be configured to generate interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself. The self-test capability allows the user to check the functionality of the sensor in the final application. The IIS2DH is available in a small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

The IIS2DLPC is an ultra-low-power high-performance three-axis linear accelerometer with digital I²C/SPI output interface which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers. The IIS2DLPC has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz. The IIS2DLPC has one high-performance mode and 4 low-power modes which can be changed on the fly, providing outstanding versatility and adaptability to the requirements of the application. The IIS2DLPC has an integrated 32-level first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor. The embedded self-test capability allows the user to check the functioning of the sensor in the final application. The IIS2DLPC has a dedicated internal engine to process motion and acceleration detection including free-fall, wakeup, highly configurable single/double-tap recognition, activity/inactivity, stationary/motion detection, portrait/landscape detection and 6D/4D orientation. The IIS2DLPC is available in a small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

The IIS2ICLX is a high-accuracy (ultralow noise, high stability, and repeatability) and low-power, two-axis linear accelerometer with digital output. The IIS2ICLX has a selectable full scale of ±0.5/±1/±2/±3 g and is capable of providing the measured accelerations to the application over an I²C or SPI digital interface. Its high accuracy, stability over temperature, and repeatability make IIS2ICLX particularly suitable for inclination measurement applications (inclinometers). The sensing element is manufactured using a dedicated micromachining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers. The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit, which is trimmed to better match the characteristics of the sensing element. The IIS2ICLX has an unmatched set of embedded features (programmable FSM, machine learning core, sensor hub, FIFO, event decoding, and interrupts), which are enablers for implementing smart and complex sensor nodes that deliver high accuracy and performance at very low power. The IIS2ICLX is available in a high-performance (low-stress) ceramic cavity land grid array (CCLGA) package and can operate within a temperature range of -40 °C to +105 °C.

The IIS2MDC is a high-accuracy, ultra-low-power 3-axis digital magnetic sensor. The IIS2MDC has a magnetic field dynamic range up to ±50 gauss. The IIS2MDC includes an I2C serial bus interface that supports standard, fast mode, fast mode plus, and high-speed (100 kHz, 400 kHz, 1 MHz, and 3.4 MHz) and an SPI serial standard interface. The device can be configured to generate an interrupt signal for magnetic field detection. The IIS2MDC is available in a plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
