Omnipolar Position Sensor ICs

Micropower SL353 Series

Omnipolar Hall-effect. SOT-23. ±60 G typ.. 1.8 μA typ.. High duty cycle (SL353HT), low duty cycle (SL353LT)

The SL353 Series sensor ICs (Integrated Circuits) are small, versatile, digital Hall-effect devices operated by the magnetic field from a permanent magnet or an electromagnet. These sensitive devices are designed to meet a wide range of potential applications with low power requirements.

The SL353 Series responds to either a North or South pole, meaning that they do not require the magnet polarity to be identified, providing an easier installation and potentially reducing system cost.

These low-power sensing devices use BiCMOS (Bipolar Complementary Metal Oxide Semiconductor) technology and a timing circuit that turns the power on for only a short time ̵1: it is off for the rest of the period (duty cycle) ̵1: significantly reducing the average current consumption.

Both products can operate from a supply voltage as low as 2.2 V, promoting energy efficiency.

The push-pull output does not require a pull-up resistor and can operate with very low current levels, potentially helping to reduce cost and minimizing the total current consumption.

The SL353 Series is available in two duty cycle configurations to accommodate a variety of application needs:

  • SL353HT: High duty cycle (13% typ.) for applications requiring high switching speed and a lower current (0.33 mA typ.) than standard Hall-effect sensor ICs.
  • SL353LT: Very low duty cycle (0.013% typ.), resulting in extended battery life in applications requiring extremely low current drain (1.8 µA typ.) and not requiring a high switching speed.

The SL353 Series has a typical operating point of ±60 Gauss at 25 °C [77 °F].

These sensors are available in the subminiature SOT-23 surface mount package on tape and reel (3000 units per reel), for use in automated pick-and-place component installation.
