Change of the operation magnetic flux density dose not depend on the supply voltage, because the stabilization power supply is built-in. (only for the range ; VCC = 4.5 to 16V) 2. Change from “H” to “L” level increases the supply current by approx. 1mA. ■ Characteristics Curve Supply Voltage – Ambient Temperature Operating Flux Density – Ambient Temperature Operating Flux Density – Supply Voltage 8 VCC =12V VCC=16V 5 4 VCC=4.5V 3 2 1 –50 –25 0 25 50 75 100 125 Output Low Level Voltage – Ambient Temperature 100 Output “L” Level Voltage (mV) to L Sample 1, BH Sample 2, BH to L 10 Sample 3, B H to L 0 Sample 1, BL to Sample 2, BL to H Sample 3, BL H –10 to H –20 Ambient Temperature (˚C) 90 20 VCC = 12V IO = 12mA 80 70 60 50 40 30 20 10 0 –50 –25 0 25 50 75 100 125 Ambient Temperature (˚C) Operating Flux Density (mT) Operating Flux Density (mT) Supply Current (mA) 6 0 Ta = 25˚C 20 7 BH to L 10 0 BL to H –10 –20 –50 –25 0 25 50 75 100 125 Ambient Temperature (˚C) 0 2 4 6 8 10 12 14 16 18 20 Supply Voltage (V)
