SS3503 Linear Hall Effect Sensor 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 SIP（suffix UA） Description put, 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. SS3503 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 set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry features low noise out- Typical Applications ─ ─ ─ ─ ─ Motor control Magnetic code reading Ferrous metal detector Current sensing Position sensing Functional Block Diagram 1 REG 1 Vcc 3 Vout 3 2 2 GND 1 V2.00 May 1, 2012 SS3503 Linear Hall Effect Sensor Pins Definition Name No Status Description Vdd 1 P Power Supply Gnd 2 P IC Ground Output 3 O Output Absolute Maximum Ratings Parameter Symbol Value Units Supply Voltage (operating) VCC 8.0 V Output Current IOUT 20 mA Operating Temperature Range TA -40~150 °C Storage Temperature Rang TS -65~150 °C Electrical Characteristics Operation Parameters TA =25°C，VCC =5.0V Parameter Symbol Test Conditions Operating voltage VCC Operating Supply current ICC Average Output Current IOUT Response Time Tack Quiescent Output Voltage Sensitivity Vo △Vout Min Typ 3.0 4.2 1.0 Max Units 6.5 V 8.0 mA 1.5 mA 3 uS B = 0G 2.25 2.5 2.75 V TA = 25°C 2.0 2.5 3.0 mV/G Min Output Voltage B = -1500G 0.86 V Max Output Voltage B = 1500G 4.21 V 2 V2.00 May 1, 2012 SS3503 Linear Hall Effect Sensor Performance Characteristics 3 V2.00 May 1, 2012 SS3503 Linear Hall Effect Sensor 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 3 0.05 ± 0.05 1.6.± 0.1 0.44± 0.01 0.38 ± 0.01 14 .5 ± 1 0.39± 0.01 Notes: 1).
