  1. RIGEL: High Temperature Adjustable 100mA Voltage Regulator

    RIGEL: High Temperature Adjustable 100mA Voltage Regulator

    The CHT-RIGEL is a high-temperature, high-reliability, 100mA adjustable linear voltage regulator suitable to generate any regulated voltage in the range +0.9V to +28V  from a standard +4.5 to 30V source.  Its typical operation junction temperature ranges from -55°C to +225°C, though it can exceed that range with some performance de-rating.

    The regulator is self-protected with a built-in over-current limitation and thermal protection which is effective in the range +250°C to +300°C.

    CHT-RIGEL brings unique benefits in applications where the ambient or operating temperature is above the temperature supported by traditional semiconductors, or in applications that operate at +155°C but require extended reliability.

    The IC features a chip-enable (CE active low) input signal allowing placing the circuit in low-power, disable mode. The output voltage is adjustable by the external resistive feedback.

    The CHT-RIGEL is a one-die solution, available in a tiny ceramic package TDFP-16 for applications where small PCB foot-print is critical.

  3. AAV003-10E -80 mA to +80 mA current sensor

    AAV003-10E -80 mA to +80 mA current sensor

    The output of the bridge voltage is bipolar and proportional to the current through the strap over a -80 to +80 mA input range. The sensing element of this device is a bridge of GMR resistors whose resistance varies with applied magnetic field. Typical sensitivity is 2mV/mA with a 24 V supply and no amplification. The sensors are targeted at circuit board current sensing for process control and instrumentation. Their sensitivity makes them ideal for isolated 4-20 mA current loop detection. These devices are suitable for both AC and DC current measurement.

    • -80 mA to +80 mA linear range
    • AC or DC Measurement
    • 2 mV/mA sensitivity
    • Ultraminiature TDFN Package
