Magnetic position sensor ICs offer high performance for small designs

New magnetic position sensor ICs from Honeywell, - the SS360NT, SS360ST, and SS460S - offer reliable, consistent performance for efficient and small designs. Encumbered with the mind-numbing product description of High Sensitivity Bipolar Latching Digital Hall-effect Sensor Integrated Circuits, the new sensors nevertheless offer reliable switching points with high magnetic sensitivity of 30 G typical (55 G maximum) without using chopper stabilization on the Hall element, resulting in a clean output signal and the fastest latch response time in its class, according to the company. .

The new ICs can be used in a wide range of applications. Potential industrial/commercial applications include brushless dc motor commutation, flow-rate sensing for appliances, speed and RPM sensing, tachometer/counter pickup, motor and fan control, and robotics control. Potential transportation applications include speed and RPM sensing, tachometer/counter pickup, motor and fan control, electronic window lifts, and convertible roof position. Potential medical applications include medical equipment that utilizes electric motors.

The devices operate over the full temperature range of -40 °C to 150 °C [-40 °F to 302 °F]. Two package styles are available: the subminiature SOT-23 surface mount package (SS360NT/SS360ST) supplied on tape and reel allows for compact design with automated component placement; the small, leaded, flat TO-92-style package (SS460S) allows for a compact PC board layout.

The new ICs offer a wide operating voltage range of 3 to 24 Vdc, allowing for potential use in a wide range of applications. Built-in reverse voltage enhances the protection of the sensor and the circuits. Their durable design allows operation up to 150 °C [302 °F]. Additionally, RoHS-compliant materials meet Directive 2002/95/EC.
