Honeywell Technologies Surface Hall Effect Sensor Digital Position Sensor Omnipolar 1.65V-5.5V SOT-23 3-Pin SM353LT

Honeywell SM353LT Surface Hall Effect Sensor is a digital, omnipolar position sensor IC designed for reliable detection of magnetic fields without the need for polarity identification. It belongs to Honeywell's Nanopower series of magneto resistive sensor ICs featuring ultra-sensitive operation, accommodating applications with wide air gaps and low power requirements.

Operating from a minimum supply voltage of 1.65 V up to 5.5 V, the sensor offers extremely low supply current consumption of 360 nA, enhancing energy efficiency in portable and industrial applications.

The sensor utilizes a push-pull output stage that simplifies system design by eliminating the need for an additional pull-up resistor. It is built to operate over a broad temperature range from -40°C to 85°C, ensuring stability in harsh environments.

Its compact SOT-23 surface mount package with 3 pins, and dimensions 2.9 mm (length) × 2.8 mm (width) × 1.4 mm (height) allows for seamless integration into PCB designs.

This Hall effect sensor is RoHS compliant, supporting environmentally conscious manufacturing processes. Typical use cases include position sensing in industrial controls, consumer electronics, HVAC systems, and automotive non-critical applications (though it does not conform to automotive standards).

The sensor is omnipolar, responding to both north and south magnetic poles. Designed for energy-efficient applications requiring minimal current draw. Compact surface mount SOT-23 package for space-saving PCB layouts. Wide operating temperature range ensures functional reliability in diverse environments.

Push-pull output for simplified external circuitry. RoHS compliant construction aligns with global environmental standards. Integration flexibility with 3-pin design supports various electronic designs.

The Honeywell SM353LT is well-suited for integration into motion sensor IC applications within industrial, laboratory, and commercial electronics sectors. For additional technical documentation and 3D models, consult Honeywell's official resources or trusted electronic component distributors.
