Digital Hall-Effect Sensor Integrated Circuits
Honeywell Sensing and Control’s new SS360PT and SS460P High Sensitivity Latching Hall-Effect Sensor Integrated Circuits (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.
The SS360PT/SS460P Hall-Effect sensors provide reliable switching points with a high magnetic sensitivity of 30 Gauss typical, at 25 C [77 F], and 55 Gauss maximum over the full -40 C to 125 C [-40 F to 257 F] temperature range, allowing for the use of smaller magnets or a wider air gap. These sensor ICs do not use chopper stabilization on the Hall element, providing a cleaner output signal and a faster latch response time when compared to competitive, chopper-stabilized, 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: 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 3 Vdc to 24 Vdc 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 125 C [257 F].
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).
