In summary, Honeywell has expanded its Hall-Effect sensor portfolio with the new SL353 series Micropower Omnipolar Digital Hall-Effect Sensor ICs that promote energy efficiency and help reduce PC board space and manufacturing costs for the customer. The SL353 series Sensor ICs 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. Additionally, they feature a built-in timing circuit that turns the power to the IC on for very short bursts of time to balance the duty cycle, significantly reducing average current consumption. The SL353 series parts 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 total system cost. These low-power sensing devices use BiCMOS (Bipolar Complementary Metal Oxide Semiconductor) technology that makes it possible to add more performance and functionality while reducing the IC size compared to bipolar technology.
