| Hall IC (Operating Temperature Range Topr=-40 to+ 100C, Operating in Alternative Magnetic Field) s Overview The DN8899/SE/TE/S is a combination of a Hall element, amplifier, Schmidt circuit, and stabilized power supply/temperature compensator integrated on an identical chip by using the IC technology. It amplifies Hall element output at the amplifier, converts into a digital signal through the Schmidt circuit, and drives the TTL or MOS IC directly. 4.00.3 10.50.5 0.80.1 0.7 DN8899/SE/TE/S DN8899 4.50.3 1.0 2.00.3 Unit : mm 5 0.50.1 1.27 123 5 2 5 2 4.520.3 4.520.3 (1.0) 2 0.43 - 0.05 1 : VCC 2 : GND 3 : Output SSIP003-P-0000A (E-3S) Unit : mm +0.1 DN8899SE s Features * High sensitivity and low drift * Stable temperature characteristics due to the additional temperature compensator 0.550.15 45 * Wide operating supply voltage range(VCC=4.5 to 16V) * Operating in alternative magnetic field * TTL and MOS ICs directly drivable by output * Semipermanent service life due to no contact parts * Small change of the operating flux density against mechanical stress 0.40.1 (1.0) 12.506.5 (0.72) * Output open collector * "0" gauss point in the zero cross type hysteresis width 1.27 2 to 5 123 2 (0.4) 1.540.1 1 : VCC 2 : GND 3 : Output Unit : mm (0.6) s Applications * Speed sensors * Position sensors * Rotation sensors * Keyboard switches * Microswitches Note) This IC is not suitable for the car electric equipment.

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. s Characteristics Curve Supply Voltage - Ambient Temperature Operating Flux Density - Ambient Temperature 8 VCC=12V 7 20 20 to L Sample 1, BH Sample 2, BH to L Operating Flux Density - Supply Voltage Ta=25C Operating Flux Density (mT) Supply Current (mA) 6 VCC=16V 5 4 VCC=4.5V 3 2 1 0 Operating Flux Density (mT) BH to L 10 10 Sample 3, B 0 H to L H Sample 1, BL to 0 BL to H -10 -10 Sample 2, BL to H Sample 3, BL to H -20 -50 -25 0 25 50 75 100 125 -50 -25 0 25 50 75 100 125 -20 0 2 4 6 8 10 12 14 16 18 20 Ambient Temperature (C) Ambient Temperature (C) Supply Voltage (V) Output Low Level Voltage - Ambient Temperature 100 90 VCC=12V IO=12mA Output "L" Level Voltage (mV) 80 70 60 50 40 30 20 10 0 -50 -25 0 25 50 75 100 125 Ambient Temperature (C) |
