Product Announcement

Packaged in an ultraminiature, four-pin, 1.1 millimeter by 1.1 millimeter by 0.45 millimeter Ultra Leadframe Land Grid Array (ULLGA) leadless package, the BD020 is NVE’s smallest packaged part. For wire bonding assembly, 0.625 mm x 0.625 mm bare die are also available.

The integrated circuit consists of a GMR sensor element, CMOS signal processing circuitry to convert the analog sensor element output to a digital output, and oscillator and timing circuitry for power management duty cycling.

Configured as a magnetic switch, the sensor output turns on when a magnetic field is applied and turns off when the field is removed. The minimum magnetic operate point is 10 oersteds (one millitesla). The applied magnetic field can be of either polarity, and the magnetic operate point is extremely stable over supply voltage and temperature.

Supply voltage range is 2.4 to 3.6 volts. The part is internally duty cycled at approximately 0.1 percent to conserve power, and typical power consumption is a remarkable 72 nanowatts at 2.4 volts. Worst-case power consumption is 576 nanowatts at 3.6 volts. An integrated latch ensures the output is available continuously. The output is current-sinking, and can sink up to 100 microamps.

Compared to reed switches, BD020 sensors feature smaller size, more magnetic sensitivity, more precise operate points, and inherent solid state reliability. Ideal applications include battery-powered implantable devices such as pacemakers, ICDs, neurostimulators, and drug pumps.

NVE is a leader in the practical commercialization of spintronics, a nanotechnology that relies on electron spin rather than electron charge to acquire, store and transmit information. The company manufactures high-performance spintronic products including sensors and couplers that are used to acquire and transmit data. NVE has also licensed its spintronic magnetoresistive random access memory technology, commonly known as MRAM.
