EMCORE's Indium Antimonide (InSb) Hall/IC Precision Switch Preliminary Information - Product Release Scheduled for April, 2000 EMCORE's InSb Hall/IC is a fully integrated solid state switch, which is turned on and off by a change in magnetic field applied vertically to the surface of the device package. Combining EMCORE's highly sensitive InSb Hall element with a high performance Hetero-Bipolar Transistor (HBT) integrated circuit on a single chip creates a state of the art, cost-effective switch with performance specifications never before possible. Precise low magnetic field switch points, narrow hysteresis band, consistent device to device performance, and robust operation differentiates the InSb Hall/IC from reed switches and other Silicon based solid state switches. Performance Features Ground The performance features of the InSb Hall/IC enable: * * * * * Simplified system design Larger operating airgaps Smaller activation magnets More predicable and reliable system operation Reduced overall system cost SOT23 Supply Low power consumption and robust operation make this switch ideal for battery powered electronic applications such as cell phones, laptop computers, pagers, and other portable electronic appliances. Output Figure 1: Typical Component Layout Application of a magnetic field above BOP will turn the output ON, while reduction in field below BRP turns the output OFF. The device will operate independent of magnetic field polarity. High performance materials and state-of-the-art device processing ensures consistent BOP and BRP switch points over temperature and from device to device.
