Servers

 

Kinetic Technologies offers a range of power management solutions to aid in design of computer server equipment.  Display and lighting products cover RGB LED control for indicator lamps.  Power interface load switches a external port over voltage and power surge shutdown protection.  To simplify Ethernet port design for EMI suppression, a unique active EMI/ESD suppression IC is available to replace passive components in this application.

 

+ Power Interface  

 

Servers employing USB or other external data ports are subject to voltage surge conditions that can potentially damage the device.  Server equipment may also need internal voltage rail switching to reduce standby power consumption or to enable/disable specific function circuits while the equipment is operating.

 

Over-voltage, transient and voltage surge protected load switches protect server equipment port circuits in the event the device is connected to a faulty system.

 

  • Programmable over voltage protection (OVP) shutdown thresholds
  • Source voltage protection to 100V
  • Transient voltage protection compliant to IEC61000-4-2 (Level 4)
  • ESD protection compliant to ±8kV contact, ±15kV air gap and ±2kV human body model.
  • Power interface switches can provide shutdown reverse or bi-directional current blocking to prevent damage to the system or circuits should a short occur at the external power port.

 

Integrated load switches provide internal power switching and are directly controlled by microcontroller logic.

 

  • 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.

+ RGB LED Drivers  

 

Multicolor RGB LEDs are often used for function indicator lamps in server systems.  Indicator lamps show power and function status for equipment that do not have detailed information displays.  Implementing indicator lamp LED control circuits to interface LED control switching to microcontroller logic is tedious for designs and requires multiple discrete components.

 

  • RGB LED drivers allow simplified programmable control of LED color and brightness in an ultra small footprint package device. 
  • 3-channel RGB LED drivers permit brightness and color control for a single RGB LED.  These devices may also control 3 discrete LEDs with one IC package device that only requires a single programming input signal for all three LEDs
  • 4-channel RGBW devices allow for driving a white LED in addition to the RGB LED or four discrete LEDs.
  • Programming interface options include ExpressWire or I2C to ease integration with a wide variety of processors and operating systems.

+ EMI/ESD Suppression  

 

Network server equipment EMC compliance for Ethernet ports often challenge the designer. Kinetic Technologies’ AS1602 is an active ESD and EMI suppressor IC intended to resolve these problems and replace large and costly passive components.  The AS1602 is a 4-channel device that connects each channel to one wire of the two Ethernet twisted pair sets.  ESD performance, EFT-B and surge immunity, and CM emissions equal to or exceed passive techniques while occupying a much smaller circuit board footprint.

 

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.
