The KSY 46 is a MOVPE1) Hall sensor made of monocrystalline GaAs-material, built into a SMT package (MW-6). The sensor is outstanding for its high magnetic field sensitivity and its very low temperature coefficients. While the sensor is operated with constant current, the output Hall Voltage is directly proportional to a magnetic field acting prependicular to the surface of the sensor. The 0.35 x 0.35 mm2 chip is mounted onto a non-magnetic leadframe. 1) Metal Organic Vapour Phase Epitaxy Semiconductor Group 1 1998-11-13 1.3 0.1 KSY 46 Maximum Ratings Parameter Operating temperature Storage temperature Supply current Thermal conductivity, soldered in air Characteristics (TA = 25 C) Nominal supply current Open-circuit sensitivity Open-circuit Hall voltage Symbol Value - 40 ... + 150 - 50 ... + 160 10 2.2 1.5 Unit C C mA mW/K mW/K TA Tstg I1 GthC GthA I1N KB0 V20 VR0 7 150 ... 265 105 ... 185 15 mA V/AT mV mV I1 = I1N, B = 0.1 T Ohmic offset voltage I1 = I1N, B = 0 T Linearity of Hall voltage B = 0...0.5 T B = 0...1.0 T Input resistance Output resistance B=0 T B=0 T Temperature coefficient of the open-circuit Hall-voltage I1 = I1N, B = 0.1 T Temperature coefficient of the internal resistance B=0 T Temperature coefficient of ohmic offset voltage I1 = I1N, B = 0 T Switch on-drift of the ohmic offset voltage I1 = I1N, B = 0 T Noise Figure FL FL R10 R20 TCV20 0.2 0.7 600 ... 900 1000 ... 1500 - 0.03 % % %/K TCR10, R20 0.3 %/K TCVR 0 0.3 %/K dV01) V02) F 0.3 0.1 10 mV mV dB 1) dV0 = | V0 (t = 1 s) - V0 (t = 0.1 s) | 2) V0 = | V0 (t = 3 m) - V0 (t = 1 s) | Semiconductor Group 2 1998-11-13 KSY 46 Connection of a Hall Sensor with a Power Source Since the voltage on the component must not exceed 10 V, the connection to the constant current supply should only be done via a short circuit by-pass. The by-pass circuit-breaker shall not be opened before turning on the power source. This is to avoid damage to the Hall sensor due to power peaks. Semiconductor Group 3 1998-11-13 |
