Micropower Omnipolar Digital Hall-effect Sensor ICs SL353 Series Datasheet

Micropower Omnipolar Digital Hall-effect Sensor ICs Micropower Omnipolar Digital Hall-effect Sensor ICs, SL353 Series, are small, and 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 including battery-operated equipment. The SL353 Series devices respond 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 – it is off for the rest of the period (duty cycle) – significantly reducing the average current consumption. Micropower omnipolar digital Hall-effect sensor ICs 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 a subminiature SOT-23 surface mount package on tape and reel (3000 units per reel), for use in automated pick-and-place component installation. What makes our sensors better? Energy efficient Supply voltage as low as 2.2 Vdc, combined with very low average current (1.8 μA typ. for SL353LT the lowest in its class), reduces power consumption, provides extended battery life, and promotes energy efficiency. Push-pull output does not require external pull-up resistor Simplifies interface with common electrical circuits and likely reducing PCB (Printed Circuit Board) space and costs to the customer. Non-chopper stabilized design Does not utilize chopper stabilization, eliminating the noise generated by products using this technique. Customers do not need filters to eliminate the chopper noise, helping to reduce PCB (Printed Circuit Board space, part counts, and costs for the application.

Honeywell recommends that the application circuit designer allow 10 μs after apply voltage has reached its rated value for the output voltage to stabilize. • The sensor will turn LOW when the magnetic field is present and switch to HIGH when the field is removed.
