Building Automation

 

Building automations devices encompass thermostat / HVAC controls, WiFi Linked Sensors, Lighting Control, Doorbells and Security Systems.  These devices can be line powered, supplied by Power over Ethernet (PoE), battery powered or utilize battery backup.  Power management is needed for PoE, display backlights, RGB LED indicator lamps, load switching and voltage regulation.

 

+ EMI/ESD Protection  

 

The AS1602 is an integrated ESD and Common Mode EMI suppression IC used to improve EMC performance in Ethernet applications.  It is built around Kinetic Technologies’ patented and proprietary Active EMC suppression technology to enable "Design for Compliance" approach to system design right from the start.  This product helps eliminate EMC compliance challenges by providing consistent EMC performance and improvements utilizing silicon based technology as opposed to passive technologies.  The AS1602 enables system designers to comply with:

 

  • CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted Emissions.
  • IEC 61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher.
  • IEC 61000-4-2 ESD (Air Discharge) of ±25kV.
  • IEC 61000-4-2 ESD (Contact Discharge) of ±12kV.
  • Cable Discharge Event (CDE) of ±12kV.

+ Voltage Regulation  

 

Products designed for building automation purposes need voltage rail on/off control to reduce standby or shutdown state power consumption or to enable/disable specific function circuits while the device is operating.

 

  • In the past, voltage rail switching required numerous discrete components that had to me tailored to design requirements costing design time and PCB space.
  • Integrated load switches provide simplified microcontroller I/O controlled power switching to eliminate the need for bias and level shift circuits associated with discrete MOSFET switches.
  • Load switches also provide slew rate limited turn on and shutdown mode reverse current blocking.

+ PoE PD Controllers  

 

Applications requiring PoE typically need high efficiency power conversion, small PCB area and reduced component count. Kinetic Technologies offers a broad portfolio of product solutions which integrate the PD physical interface and DC/DC controller functions into a single package. Supporting solutions from a few watts up to the maximum allowed, Kinetic Technologies provides high efficiency power solutions for nearly every PoE PD application.

 

  • The AS11xx family of parts support single output isolated or non-isolated solutions for IEEE802.3af (Type 1) and IEEE802.3at (Type 1 and Type 2) PDs or higher power levels using custom programmed PSEs or by implementing the LLDP to enable 4-pair power delivery on the Ethernet cable.
  • The AS18xx family of parts support single and multi-output isolated solutions for IEEE802.3af (Type 1) and IEEE802.3at (Type 1 and Type 2) PDs or higher power levels using custom programmed PSEs or by implementing 4-pair power delivery. The AS18xx family, in addition to integrating the PD physical interface and DC/DC controller functions, adds synchronous rectifier control and integrated digital signal isolation thereby eliminating the need for opto-couplers. The multi-output versions support up to three additional outputs, each of which may be individually sequenced. All products include input and output over-current protection, output over-voltage protection, and over-temperature protection.
  • The AS18xx family has full command/control and monitoring capability available through the integrated I2C bus, which allows management of the power processing functions such as on/off control, voltage margining, sequencing of outputs, fault and alarm monitoring, and even input voltage and current.

+ RGB LED Drivers  

 

Building automation equipment use multicolor RGB LEDs for function indicator lamps.  Indicator lamps show power on or system connectivity on devices that use LCD displays.  For devices without displays, indicator lamps are needed to show power and status for all functions.

 

  • RGB LED drivers allow programed control of LED color and brightness in an ultra small footprint package device. 
  • Kinetic Technologies’ devices feature a wide range of ramp up/down timing for slow fade in/out effects and complex repeating patterns.
  • 3-channel RGB LED drivers permit customer color control
  • 4-channel RGBW devices allow for driving a white LED in addition to the RGB LED.
  • Programming interface options include ExpressWire or I2C to ease integration with a wide variety of processors and operating systems.
