Linear Hall-effect Sensor ICs: 055843 Datasheet SS490 Series Issue 2 Datasheet FEATURES • Linear output for circuit design flexibility • Quad-Hall IC design minimizes mechanical stress effects • Responds to either positive or negative Gauss • Uses 7 mA at 5 Vdc for energy efficiency • Single current sinking or current sourcing output • Rail-to-rail operation provides more usable signal for higher accuracy • Temperature-compensated magnetics help provide stable operation over a wide temperature range of -40°C to 150°C [-40°F to 302°F] POTENTIAL APPLICATIONS Industrial: • Basic current sensing for motor load monitoring, detection DESCRIPTION The SS490 Series are small, versatile, linear Hall-effect • Anti-tampering magnetic field sensor in smart remote utility devices which are operated by the magnetic field from a meters permanent magnet or an electromagnet. The ratiometric • Pump control in heavy-duty equipment and household output voltage is set by the supply voltage and varies appliances in proportion to the strength of the magnetic field. The • Simple linear or angular displacement sensing integrated circuitry provides increased temperature stability • Handlebar/throttle position sensing in e-bikes and scooters and sensitivity. Laser-trimmed, thin film resistors provide high • Current sensing in appliances accuracy (null to ±%, sensitivity up to ±3%) and temperature • Speed adjustment trigger in tools and appliances compensation. They respond to either positive or negative • Magnetic code reading in safes, security and building Gauss, monitoring either or both magnetic poles. The quad access control systems Hall sensing element minimizes the effects of mechanical Medical: Position sensing in infusion pumps or thermal stress on the output. The positive temperature coefficient of the sensitivity (+0.02%/°C typical) helps PORTFOLIO compensate for the negative temperature coefficients of The SS490 Series and the SS39ET, SS49E, SS59ET Linear low-cost magnets, providing a robust design over a wide Hall-effect Sensor ICs form Honeywell’s Linear Hall-effect temperature range. Rail-to-rail operation (over full voltage Sensor IC offering. range) provides a more usable signal for higher accuracy. These products have an operating temperature range of -40°C to 150°C [-40°F to 302°F], appropriate for industrial and automotive environments. The SS490B versions offer cost-effective sensing solutions with wider null and sensitivity tolerances, and a wider drift over temperature than the SS490A higher performance products. Both the SS490A and SS490B versions have a typical sinking or sourcing output of 1.5 mA continuous, use 7 mA supply current at 5.0 V at 25°C [77°F], and provide predictable performance over the full temperature range. For design flexibility, these products are available in the following flat TO-92 package styles: • SS4XX: Straight standard leads, bulk pack • SS4XX-L: Straight long leads, bulk pack • SS4XX-T2: Formed leads, ammopack tape-in-box • SS4XX-T3: Straight standard leads, ammopack tape-in-box • SS4XX-S: Surface mount, bulk pack • SS4XX-SP: Surface mount, pocket tape and reel Sensing and Internet of Things
