3 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

4 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

5 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

6 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
