DN8798MS

Hall ICs DN8798MS 3 V operation Hall IC s Overview The DN8798MS is a 3 V operation Hall IC which includes a Hall element, amplifier circuit, Schmidt circuit, stabilized power supply and temperature compensation circuit which are integrated on a single chip with a fine patterning technology. The magnetic input signal is outputted by being converted to high or low. We have improved the conventional circuit to realize a stable operation covering from low to high supply voltage and from low to high temperature. 10° + 0.20 0 to 0.1 1.10 – 0.10 0.30 1.10 + – 0.10 Unit: mm 1.45 0.10 0.40 + – 0.05 0.65 ± 0.15 0.10 0.16 + – 0.06 3 0.25 1.50 + – 0.05 0.20 2.80 + – 0.30 1 0.95 2 0.65 ± 0.15 0.95 1.90 ± 0.20 + 0.20 2.90 – 0.05 s Features Wide operating supply voltage range (VCC = 2.7 V to 14.4 V) Wide operating ambient temperature (−40°C to +85°C) Package: Mini type (3-pin type) (1.1 mm thick: Same as a standard transistor) MINI-3D s Applications DC brushless motor, fan motor, rotation sensor, detection of cover open/close (example for a cellular phone), position sensor s Block Diagram VCC Constant voltage source 2 5° Comparator Hall element Amplifier 1 Out GND 3 0.40 ± 0.20 1 DN8798MS s Pin Descriptions Pin No. 1 2 3 Symbol Out VCC GND Description Output pin Supply voltage pin Ground pin Hall ICs s Absolute Maximum Ratings Parameter Supply voltage Symbol VCC VOUT Supply current Power dissipation Operating ambient temperature Storage temperature ICC PD To...
