Change of the operation magnetic flux density does 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 22.5 Operating flux density (mT) Supply current (mA) 7 6 5 VCC = 16V 4 VCC = 4.5V 3 2 1 0 –50 –25 0 25 50 75 100 Output low level voltage – Ambient temperature 100 Output “L” level voltage (mV) 20.0 20.0 VCC = 4.5 to 16V BH→L Ta =25˚C 17.5 le 1 Samp 17.5 15.0 Sam 12.5 10.0 ple 2 Sample 3 Sample 4 7.5 5.0 VCC =12V IO =12mA 80 70 60 50 40 30 20 10 0 –50 –25 0 25 50 75 100 125 Ambient temperature (˚C) 15.0 12.5 10.0 7.5 5.0 2.5 2.5 Ambient temperature (˚C) 90 Operating flux density – Supply voltage 25.0 Operating flux density (mT) 8 –50 –25 0 25 50 75 100 Ambient temperature (˚C) 0 0 2 4 6 8 10 12 14 16 18 20 Supply voltage (V) Request for your special attention and precautions in using the technical information and semiconductors described in this material (1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of the products or technologies described in this material and controlled under the "Foreign Exchange and Foreign Trade Law" is to be exported or taken out of Japan.
