  • Clamps transients on both avionics and industrial power busses
  • Permits use of a variety of power supplies and OP Amps
  • Small foot print (8L SOIC NB)
  • Wide input voltage range
  • Programmable Undervoltage Lockout
  • Stable over temperature
  • Active low On/Off Pin
  • Soft start
  • Highly versatile

The DEI 1028 is designed to provide the control for a power supply voltage clamp. It provides drive for a wide variety of P-Channel MOSFETS, linearly clamping the output. There is also a programmable Undervoltage Lockout feature that shuts the Power MOSFET off. Output voltage is maintained below the clamping threshold for Commercial-Off-The-Shelf switching supplies and op amps. If the clamping threshold is exceeded the out-put voltage is clamped at 35V maximum. The device is protected against a 100V spike of 100ms duration with over and undershoot protection

An open collector logic output is also provided that can be used as a power down interrupt for the system micro-processor.

  • Emulates incandescent lamp "Square Law" luminance curve.
  • LED dimming controlled by Pulse Width Modulation ranging from 50HZ to 200HZ.
  • LED current adjustable from 10mA to 20mA.
  • 200:1 Dimming Range at 50Hz. 40:1 Dimming Range at 200Hz
  • Drives 8 LED outputs with matched current drive.
  • Drivers can be cascaded to synchronously drive additional LEDs.
  • Plastic 16 lead SOIC package.

The DEI1090 device is a 16 pin bipolar integrated circuit designed to drive nine LEDs and provide Pulse Width Modulated (PWM) dimming control according to the luminance curve of incandescent lamps. The device squares the analog control input and produces a PWM waveform used to enable or disable the current outputs. The LED brightness is controlled by the PWM duty cycle. All nine LEDs are driven at the same adjustable drive current. Drivers can be cascaded to synchronously drive additional LED groups. The dimming control input may be a DC or AC voltage.
