Honeywell Expands Portfolio With New SS39ET Series Linear Hall-Effect Magnetic Position Sensor IC

Honeywell » SS39ET, SS49E, SS59ET

Low-cost, Versatile SOT-23 Subminiature Surface Mount Package Ideal for Compact Designs with Tight Space Requirements

Honeywell is extending its Linear Hall-effect Sensor Integrated Circuits (IC) product line with the addition of the new SS39ET Series to its SS49E and SS59ET portfolio of low-cost Linear Hall-effect devices.

With the launch of the SS39ET Series, Honeywell’s Linear Hall-effect product family now consists of three package styles with different lead configurations:

  • SS39ET: subminiature SOT-23 surface mount package (tape and reel format)
  • SS49E: leaded flat TO-92 package (bulk packaging, 1000 units per bag), SS49E-T2 (straight leads), and SS49E-T3 (formed leads) on tape in ammopack (fan-fold) format
  • SS59ET: miniature SOT-89B surface-mount package (tape and reel format)

The SS39ET Series are designed to monitor magnetic fields from a permanent magnet or an electromagnet. All packages can be supplied on tape for automated, lower-cost assembly. These devices respond to both North and South poles, and can be powered with voltages as low as 2.7 V.

A wide temperature range of -40 °C to 100 °C [-40 °F to 212 °F] allows use in many environments, and the thermally balanced, integrated circuit provides stable operation over the full temperature range. Thin film resistors improve accuracy and provide a stable output. The energy-efficient, low current consumption of 6 mA at 5 Vdc and the 2.7 Vdc to 6.5 Vdc supply voltage range allow circuit design flexibility.
Potential industrial applications for the SS39ET Series include:

  • Anti-tampering magnetic field sensing in smart remote utility meters
  • Basic current sensing for motor load monitoring, detection
  • Pump control in heavy-duty equipment and household appliances
  • Simple linear or angular displacement sensing
  • Handlebar/throttle position sensing in e-bikes and scooters
  • Current sensing in appliances
  • Speed adjustment trigger in tools and appliances
  • Magnetic code reading in safes, security, and building access control systems.

Potential medical applications for the SS39ET Series include:

  • Position sensing in infusion pumps
