Introduction Honeywell offers a variety of Linear Hall-effect Sensor ICs to meet a wide range of industrial and medical application needs They are designed to monitor magnetic fields from a permanent magnet or an electromagnet Honeywell has engineered these devices to enable top performance, precision, repeatability, and ruggedness Various package styles include: Subminiature SOT-23: SS39ET (new) Flat TO-92 straight leads: SS49E, SS49E-L, and SS49E-T3 Flat TO-92 formed leads: SS49E-F and SS49E-T2 SOT-89: SS59ET Various packaging options include tape and reel, bulk packaging, and tape in box (ammopack) 3 Honeywell Linear Hall-effect Sensor ICs

Features and Benefits Honeywell s Linear Hall-effect Sensor ICs offer many features and benefits, including: Cost-effective Designed and manufactured for cost competitiveness All packages can be supplied on tape for automated, lower-cost assembly Miniature and sub-miniature construction SS39ET s small footprint takes up little space on the PC board, often ideal for compact designs with tight space requirements Small size typically allows for more components to be placed onto the board Flexible Interfaces with many electrical components without buffering Responds to either positive or negative Gauss Responds to both North and South poles Stable and accurate Thermally balanced integrated circuit allows for stable operation and accuracy over the full temperature range 4 Honeywell Linear Hall-effect Sensor ICs

Features and Benefits (continued) Energy efficient Low voltage capability as low as 2.7 Vdc and reduced current consumption of only 6 ma at 5 Vdc help make these products energy efficient Easy PC board interface Single current sourcing output for common electronic circuits Low noise output Virtually eliminates the need for external filtering Wide operating temperature range Temperature range of -40 C to 100 C [-40 F to 212 F] allows for use in a wide range of environments 5 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial Honeywell s Linear Hall-effect Sensors may potentially be used in several Industrial applications, including: Tamper prevention in utility meters Thieves sometimes attempt to bypass the operation of an electric, gas or water meter by attaching a strong magnet to it. The utility usage is underestimated when the magnet saturates the current transformer or slows the spinning wheel. Install Honeywell s Linear Hall-effect Sensor ICs in multiple locations inside the meter to detect the abnormal presence of a magnetic field. Send an alarm to the utility company or record this fraudulent activity in memory for access at a later date. 6 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial (continued) Scooters and electric bikes Honeywell s Linear Hall-effect Sensor ICs may be used to detect handlebar and throttle position on scooters and e-bikes 7 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial (continued) Magnetic code reading in safes, security, and building access control systems A secure electronic lock can be designed using an array of linear magnetic sensors configured to detect a magnetic pattern. If a strong external magnet were brought in proximity to the array, it would be read as a random attempt and could trigger an alarm Honeywell s Linear Hall-effect Sensor ICs may be used to unlock the system only if the magnetic field read by each sensor is of the correct polarity and within acceptable amplitude limits Without reproducing the exact magnetic flux pattern, it would be virtually impossible to unlock the system with a single, or even multiple, strong magnets Honeywell s Linear Hall-effect Sensor ICs provide sensitivity, output, and very small size 8 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial (continued) Speed adjustment in tools and appliances Honeywell s Linear Hall-effect Sensor ICs may be used as a speed adjustment trigger in tools and appliances 9 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial (continued) Water pump control in heavy-duty equipment and appliances A water pump is essentially a special application of an electric motor; these pumps are commonly manufactured for home appliances Honeywell s Linear Hall-effect Sensor ICs may be used to generate an enhanced control signal for better resolution of the rotor position, which can improve the motor's efficiency A crude RPM measurement would verify that the pump is working properly; the output of the sensor may be used as an alarm or a shut-off signal to help prevent motor overload 10 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial (continued) Pump control in aquariums A pump may use one or more valves, engage a clutch or gear to begin, or move a lever or piston a specified distance Honeywell s Linear Hall-effect Sensor ICs may be used to verify that the valve, clutch, lever or piston is in the specified position 11 Honeywell Linear Hall-effect Sensor ICs

Potential Applications Industrial (continued) Current sensing in motors Honeywell s Linear Hall-effect Sensor ICs may be used for basic current sensing for motor load monitoring and detection Current sensing in appliances Honeywell s Linear Hall-effect Sensor ICs may be used to monitor the current powering the electromagnets in the appliance s motor If the current is not within its normal range, the logic could also perform overload or motor malfunction detection 12 Honeywell Linear Hall-effect Sensor ICs
