Silicon Laboratories’ Si4455 is an easy-to-use, low current, sub-GHz EZRadio transceiver.
Covering all major bands, it combines plug-and-play simplicity with the flexibility needed to handle a wide variety of applications. The compact 3x3 mm package size combined with a low external BOM count makes the Si4455 both space efficient and cost effective. The +13 dBm output power and excellent sensitivity of –116 dBm allows for a longer operating range, while the low current consumption of 18 mA TX (at 10 dBm), 10 mA RX, and 50 nA standby, provides for superior battery life. By fully integrating all components from the antenna to the GPIO or SPI interface to the MCU, the Si4455 makes realizing this performance in an application easy.

Design simplicity is further exemplified in the Wireless Development Suite (WDS) user interface module. This configuration module provides simplified programming options for a broad range of applications in an easy to use format that results in both a faster and lower risk development. Like all Silicon Laboratories’ EZRadio devices, the Si4455 is fully compliant with most worldwide regulatory standards such as FCC, ETSI, and ARIB.

Silicon laboratories have just release the Si7005, a digital relative humidity and temperature sensor. This monolithic CMOS IC integrates humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data and an I2C host interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of a low-power, monolithic CMOS sensor IC with low drift and hysteresis and excellent long term stability. Both the humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required, simplifying designs and reducing end system manufacturing costs. The Si7005 humidity and temperature sensor is packaged in a 4 mm x 4 mm QFN package and is reflow solderable. The solution only requires 2 external SMD capacitors. Some of the key features are:

  • Relative Humidity Sensor: ± 4.5% RH (maximum @ 20–80% RH)
  • Temperature Sensor: ±0.5 ºC accuracy (typical) / ±1 ºC accuracy (maximum @ 0 to 70 °C)
  • 0 to 100% RH operating range
  • –40 to +85 ºC (-GM – wide temp range version)
  • 0 to +70 ºC operating range (-FM – normal temp range version)
  • Wide operating voltage range (2.1 to 3.6 V)
  • Low Power Consumption: 240 μA during RH conversion
  • I2C host interface

MP4690 is a MOSFET based smart bypass for LED open protectionThe MP4690 is a MOSFET based smart bypass for LED open protection, which provides a current bypass in the case of a single LED fails and becomes an open circuit. When the LED heals itself or is replaced, the MP4690 automatically resets. This device features very low voltage drop so that the conduction loss is very small during the protection. It achieves excellent thermal performance and energy efficiency. LED lighting requires high reliability, especially in applications, such as automobiles, aircrafts, and streetlights. The MP4690 is used in parallel with each LED so that when one LED fails, other LEDs in the same string can still function normally. The usage of the MP4690 is not limited to just LED loads. It can also be used with other loads where open protection is required. The MP4690 is typically used with 1W-2W. LEDs. The device is available in a SOD123 package.
