ZMC05 CURRENT SENSOR DESCRIPTION The ZMC05 allows the measurement direct or alternating current up to 5A. It consists of a magnetic sensor chip (employing the magneto resistive effect of thin Permalloy), which measures the magnetic field generated by an internal-carrying conductor. FEATURES Package : SM-8 Supply voltage 12 V No Auxiliary Field Required Measurable current I up to 5A M Available on 12mm tape APPLICATION Contactless and free from losses current measurement PINOUT DIAGRAM Automotive 1 8 Battery Power Equipment Power Supplies 2 7 Electric Motor Control Power Management 3 6 ORDERING INFORMATION 4 5 DEVICE REEL TAPE QUANTITY SIZE WIDTH PER REEL ZMC05TA 7 12mm 1000 PIN CONNECTION ZMC05TC 13 12mm 4000 1) Do not connect 5) -V O 2) +V 6) Current input O DEVICE MARKING 3) Current output 7) +V B ZMC05 4) -V 8) Do not connection B ISSUE 2 - MAY 2003 1ZMC05 ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL LIMIT UNIT Supply Voltage V 12 V B Measurable current 5A I M at DC: absolute value at AC: peak value Operating temperature range T -25 to +125 C amb Storage temperature range -25 to +125 C T stg ELECTRICAL CHARACTERISTICS (at T = 25 C unless otherwise stated) amb PARAMETER SYMBOL MIN.
