SS657 Unipolar Hall-Effect Digital Switch Features Miniature construction Low-Noise Output 4.5 V to 6 V Operation Magnetically Optimized Package Linear output for circuit design flexibility Temperature range of -40 °C to 150 °C 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA) Functional Block Diagram 1 Application Examples – – – – – REG 1 Vcc 3 Vout 3 2 Motor control Magnetic code reading Ferrous metal detector Current sensing Position sensing General Description SS657 Linear Hall-effect sensor is small, versatile linear Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The linear sourcing output voltage is 2 GND set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry features low noise output, which makes it unnecessary to use external filtering. It also includes thin film resistors to provide increased temperature stability and accuracy. The linear Hall sensor has an operating temperature range of -40 °C to 150 °C appropriate for commercial, consumer and industrial environments. 1 V3.10 Nov 1, 2013 SS657 Unipolar Hall-Effect Digital Switch Glossary of Terms MilliTesla (mT), Gauss RoHS Operating Point (BOP) Release Point (BRP) Units of magnetic flux density: 1mT = 10 Gauss Restriction of Hazardous Substances Magnetic flux density applied on the branded side of the package which turns the output driver ON (VOUT = VDSon) Magnetic flux density applied on the branded side of the package which turns the output driver OFF (VOUT = high) 2 V3.10 Nov 1, 2013 SS657 Unipolar Hall-Effect Digital Switch Pin Definitions and Descriptions SOT Pin № Name Status Description 1 VDD P Power Supply 2 OUT P IC Ground 3 GND O Output Absolute Maximum Ratings Parameter Symbol Supply Voltage( operating) Output Current Operating Temperature Range Storage Temperature Range VCC IOUT TA TS Value Units 8.0 20 -40 to 150 -65 to 150 V mA °C °C Electrical Characteristics DC Operating Parameters TA = 25°C, VCC= 5.0V Parameter Symbol Test Conditions Min Operating Voltage Supply Current Output Current Response Time Quiescent Output Voltage Sensitivity Min Output Voltage Max Output Voltage VCC ICC IOUT Tack VO △VOUT Operating Average 3.0 1.0 B = 0G TA =25°C B = -1500G B = 1500G 2.25 2.0 3 Typ 4.2 1.5 3 2.5 2.5 0.86 4.21 Max Units 6.5 8.0 V mA mA µs V mV/G V V 2.75 3.0 V3.10 Nov 1, 2013 SS657 Unipolar Hall-Effect Digital Switch Performance Characteristics 4 V3.10 Nov 1, 2013 SS657 Unipolar Hall-Effect Digital Switch Package Information 2.13 1.87 0.75 ± 0.05 1.52 ± 0.1 Package UA, 3-Pin SIP: 3° ± 1° 1.00 1.20 45° ± 1° 4.0 ± 0.01 1 2 3 3.0 ± 0.01 Sensor Location Active Area Depth: 0.84(Nom) 3° ± 1° 6° ± 1° 3° ± 1° 6° ± 1° 1 2 0.05 ± 0.05 3 1.6.± 0.1 0.44± 0.01 0.38 ± 0.01 14 .5 ± 1 0.39± 0.01 Notes: 1).
