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 -40C to 150C -40F to 302F POTENTIAL APPLICATIONS Industrial: Basic current sensing for motor load monitoring, detection DESCRIPTION Anti-tampering magnetic field sensor in smart remote utility The SS490 Series are small, versatile, linear Hall-effect meters devices which are operated by the magnetic field from a Pump control in heavy-duty equipment and household permanent magnet or an electromagnet. The ratiometric appliances output voltage is set by the supply voltage and varies Simple linear or angular displacement sensing in proportion to the strength of the magnetic field. The Handlebar/throttle position sensing in e-bikes and scooters integrated circuitry provides increased temperature stability Current sensing in appliances and sensitivity. Laser-trimmed, thin film resistors provide high Speed adjustment trigger in tools and appliances accuracy (null to %, sensitivity up to 3%) and temperature Magnetic code reading in safes, security and building compensation. They respond to either positive or negative access control systems Gauss, monitoring either or both magnetic poles. The quad 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 Honeywells 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 -40C to 150C -40F to 302F , 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 25C 77F , 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 ThingsLinear Hall-effect Sensor ICs: SS490 Series Table 1.
