Honeywell Sensing and Control’s new SS360PT and SS460P High Sensitivity Latching Hall-Effect Sensor ICs with Built-in Pull-up Resistors are high-performance yet economical sensor ICs well-suited for demanding, cost-sensitive high-volume applications, such as commuting brushless DC motors used for medical equipment and appliances as well as for flow-rate sensing, speed and RPM sensing, tachometers, counter pickups, motor and fan controls.

SS360PT/SS460P Hall-Effect sensors provide reliable switching points with a high magnetic sensitivity of 30 Gauss typical, at 25degC (77degF), and 55 Gauss maximum over the full -40degC to 125degC (-40degF to 257degF) temperature range, allowing for the use of smaller magnets or a wider air gap. These sensor ICs do not use chopper stabilisation on the Hall element, providing a cleaner output signal and a faster latch response time when compared with competitive, chopper-stabilised, high-sensitivity Hall-effect bipolar latching sensor ICs. Latching magnetics make these sensors well suited for accurate speed sensing and RPM (revolutions per minute) measurement. Follow the link for a test comparison white paper.

The sub-miniature, SOT-23 surface mount package (SS360PT) allows for compact design with automated component placement. The small, leaded, flat TO-92-style package (SS460P) allows for a compact PC board layout design. Wide operating voltage range of 3V DC to 24V DC provides for potential use in a wide range of applications. Built-in reverse voltage capability enhances the protection of the sensor and the circuits, and the robust design allows operation up to 125degC (257degF).

Joshua Edberg, senior global marketing manager in the Magnetic Sensors division at Honeywell Sensing and Control, says: “The new SS360PT and SS460P are the industry’s best solutions for brushless DC motor manufacturers that need latching sensors with reliable, consistent performance. Honeywell’s new High Sensitivity Hall-Effect Latching Sensor ICs with built-in pull-up resistors are less costly and more compact for brushless motor designs.”

These Hall-Effect devices are available in two package styles: the SS360PT in the miniature SOT-23 surface mount package and the SS460P in the leaded, flat TO-92-style package. The SS360PT is supplied on tape and reel (3000 units per reel). The SS460P is available in a bulk package (1000 units per bag).
