| ZMY20 MAGNETIC FIELD SENSOR DESCRIPTION The ZMY20 is an extremely sensitive magnetic sensor employing the magneto-resistive effect of thin film permalloy. It allows the measurement of magnetic fields or the detection of magnetic parts. The highly sensitive and small size magnetoresistive sensors consist of a chip covered with thin film permalloy stripes. These stripes form a Wheatstone bridge, whose output voltage is proportional to the magnetic field component Hy. A perpendicular field Hx is necessary to stabilize sensor operation. This can be done by using a small permanent magnet. Hy -VB Hx +VB -VO +VO FEATURES * Output voltage proportional to magnetic field Hy * Adjustment of sensitivity and suppression of hysteresis by the auxiliary magnetic field Hx * Magnetic fields vertical to the chip level are not effective SOT223S APPLICATIONS * Linear position sensors for process control, door interlocks, proximity detectors, machine tool sensing * Scalar measurement for compassing * Automotive - door switches, engine position & speed sensing * Metering of fluids by sensing rotation of impeller * Traffic counting & vehicle-type sensing * Measurement of current in a conductor without connection PINOUT -VB ORDERING INFORMATION DEVICE ZMY20TA ZMY20TC REEL SIZE 7" 13" TAPE WIDTH 12mm 12mm QUANTITY PER REEL 1000 units 4000 units +VO -VO +VB VB = SUPPLY VOLTAGE VO = OUTPUT VOLTAGE Top View DEVICE MARKING * ZMY20 ISSUE 2 - NOVEMBER 2002 1 SEMICONDUCTORS ZMY20 ABSOLUTE MAXIMUM RATINGS PARAMETER Supply voltage Total power dissipation Operating temperature range Storage temperature range SYMBOL VB P TOT T amb T stg LIMIT 12 120 -40 to +150 -65 to +150 UNIT V mW C C ELECTRICAL CHARACTERISTICS (at Tamb=25C and HX=3 kA/m unless otherwise stated) PARAMETER Bridge resistance Output voltage range Open circuit sensitivity Hysteresis of output voltage Offset Voltage Operating frequency Temp. coeff. of offset voltage Temp. coeff. of bridge resistance Temp. coeff. of open circuit sensitivity V B =5V Temp. coeff. of open circuit sensitivity I B =3mA SYMBOL R br V O /V B S V OH /V B V off /V B f max TCV off TCR br TCS V MIN 1.2 16 3.7 -1.0 0 -3 0.25 -0.25 TYP 1.7 20 4.7 0.3 -0.3 MAX 2.2 24 5.7 50 +1.0 1 +3 0.35 -0.35 UNIT k mV/V (mV/V)/ (kA/m) V/V mV/V MHz (V/V)/K %/K %/K Tamb= -25 to +125C Tamb= -25 to +125C Tamb= -25 to +125C No disturbing field Hd allowed Hy 2kA/m TEST CONDITIONS TCS I - -0.1 - %/K Tamb= -25 to +125C ISSUE 2 - NOVEMBER 2002 SEMICONDUCTORS 2 ZMY20 Application 1 (digital output) Application 2 (analog output) ISSUE 2 - NOVEMBER 2002 3 SEMICONDUCTORS ZMY20 Sensor output characteristic VO=f(Hy); Hx-parameter Vb=const; Tamb=25C Safe operating area Hxtot=Hx + Hd; Tamb=25C; (Hd=disturbing field) The sensor has to be reset after leaving the safe operating area by an auxiliary field of Hx=3kA/m ISSUE 2 - NOVEMBER 2002 SEMICONDUCTORS 4 ZMY20 Sensor sensitivity characteristic S=f(Hx) Vb=const; Tamb=25C Supply voltage (maximum) derating curve VBmax=f(Tamb) Device mounted on 40 x 40 mm2 board (copper area 600mm2) ISSUE 2 - NOVEMBER 2002 5 SEMICONDUCTORS ZMY20 PACKAGE OUTLINE PAD LAYOUT CONTROLLING DIMENSIONS IN MILLIMETERS APPROX CONVERSIONS INCHES PACKAGE DIMENSIONS Millimeters DIM Min A A1 b b2 C 0.02 0.66 2.90 0.23 Max 1.80 0.10 0.84 3.10 0.33 Min 0.0008 0.026 0.114 0.009 Max 0.071 0.004 0.033 0.122 0.013 e e1 E E1 L Inches DIM Min Max Min Max 2.30 BSC 4.60 BSC 6.70 3.30 0.90 7.30 3.70 0.0905 BSC 0.181 BSC 0.264 0.130 0.355 0.287 0.146 Millimeters Inches (c) Zetex plc 2002 Europe Zetex plc Fields New Road Chadderton Oldham, OL9 8NP United Kingdom Telephone (44) 161 622 4422 Fax: (44) 161 622 4420 uk.sales@zetex.com Zetex GmbH Streitfeldstrae 19 D-81673 Munchen Germany Telefon: (49) 89 45 49 49 0 Fax: (49) 89 45 49 49 49 europe.sales@zetex.com Americas Zetex Inc 700 Veterans Memorial Hwy Hauppauge, NY11788 USA Telephone: (631) 360 2222 Fax: (631) 360 8222 usa.sales@zetex.com Asia Pacific Zetex (Asia) Ltd 3701-04 Metroplaza, Tower 1 Hing Fong Road Kwai Fong Hong Kong Telephone: (852) 26100 611 Fax: (852) 24250 494 asia.sales@zetex.com These offices are supported by agents and distributors in major countries world-wide.
