Voltage Clamping Circuit

Voltage Clamping Circuit

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 output 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.

LED Driver

DEI1090  LED Driver

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.

Lightning Protection

DEI components are lightning protected up to Level 3 (300V and 600V) without external resistor.

The new composite Aircraft as Airbus A350, require higher levels of protection  (Level 5 / Waveform 5A).

If it is easy to add an external resistor for high impedance I/O components, it is more problematic for ARINC 429 line driver or Discret to Digital.
The use of high power TVS poses problems of size, weight, capacitance and reliability.
DEI has just developed a new component; the DEI 1604 act as a current limiter when a lightning strike occurs. You just need to add a small TVS to ensure the voltage protection.
The DEI 1604 is a bidirectional component, consisting of 2 JFETs in series using SiC (Silicon Carbide) technology that will limit the current.
