OHS3177U

The OHS3177U is a Hall Effect device containing a monolithic integrated circuit which incorporates a hall element, a linear amplifier, a threshold amplifier and Schmitt trigger on a single Hallogic® silicon chip. Included on-chip is a band gap voltage regulator to allow operation with a wide range of supply voltages. These devices feature logic level output and provide up to 21mA of sink current. This allows direct driving of more than 7 TTL loads or any standard logic family. Output amplitude is constant at switching frequencies from DC to over 200kHz. The Bi-Polar latch device turns on (logic level "0") in the presence of a magnetic south-pole and turn off (logic level "1") when subjected to a magnetic north pole. Both magnetic poles are necessary for operation for Bi-Polar devices. This feature makes these sensors ideal for applications in noncontact switching operations, brushless DC motors and for use with multiple pole magnets.

• Designed for non-contact switching operations
• Operates with excellent temperature stability in harsh environments
• Drive capability up to 7 TTL loads
