Issue Number │001 May 2010 New Product Announcement ZXCT1082/4/6 ZXCT1083/5/7 High-side current monitors simplify measurement at high voltage The ZXCT108x are high side unipolar current sense monitors. These devices eliminate the need to disrupt the ground plane when sensing a load current. The ZXCT1082/1084/1086 have 60V maximum operating voltage and ZXCT1083/1085/1087 have 40V maximum operating voltage. The wide common-mode input voltage range and low quiescent currents coupled with SOT25 packages make them suitable for a range of applications; including automotive and systems operating from industrial 24-28V rails. They have been approved to AEC-Q100.1 The Diodes advantage The ZXCT108x family provide an accurate and simple solution to high side current measurement Wide supply and common-mode voltage range • 2.7V to 60V ZXCT1082/84/86 • 2.7V to 40V ZXCT1083/85/87 Devices will operate in wide range of different markets: • 40V supports industrial rails and computer power supplies. • 60V supports automotive load dump figures and SELV rails Independent supply and input common-mode voltage Allows currents to measured beyond the normal power supply rails Low quiescent current (0.6µA). Reduces current measurement errors associated with quiescent current Extended industrial temperate range -40 to 125°C Enables it to be used in wider range of applications and temperatures Green mold compound (No Br, Sb) SOT25 Meets latest environmentally friendly requirements in small footprint Circuit functions Over-current detection in: Power supply Automotive Motor Control Current measurement Battery charging LED Driving www.diodes.com NPA Number 001 New Product Announcement ZXCT1082/4/6 ZXCT1083/5/7 High-side current monitors simplify measurement at high voltage Current Monitor portfolio with ≥ 40V capability ROUT Outputt impedance Accuracy @ V VSENSE =100mV kΩ % µA V/V MHz Availab ble Packages Maximum Sense Voltage V AEC‐Q100 Maximum output voltage V Ambient TTemp Range Max S+ Com mmon‐ mode sense vvoltage V Band dwidth Min S+ Com mmon‐mode sense vvoltage V Gain Max Supp ply Voltage V Quiescen nt Current Min Supp ply Voltage Desscription P Part # V X SOT25 X SOT25 X SOT25 °C ≥40V Current output current monitors with externally set gain gain ZXCT1082 60V Current output Current Monitor 2 7 60 2.7 2.7 27 60 VS‐ 0 5 S ‐1 0. 5 ‐ 2 2+5 ext 05 0.5 ZXCT1083 60V Current output Current Monitor 2.7 40 2.7 40 VS‐‐1 ‐ 2 2+5 ext 0.5 ZXCT1080 60V G = 10 Current Monitor 4.5 12 3 60 30 10 0.5 3 0.5 ‐40 to +125 ≥40V Voltage output current monitors with fixed gain 1.5 0.15 ‐ 3 ZXCT1081 40V G = 10 Current Monitor 4.5 12 40 1.5 0.15 ‐ 3 30 10 0.5 ZXCT1084 60V G = 25 Current Monitor 2.7 60 2.7 60 VS‐‐1 0.5 125 2 2+5 25 0.5 ZXCT1085 40V G 25 C 40V G = 25 Current Monitor t M it 2 7 40 2.7 2.7 27 40 VS‐‐1 1 05 0.5 125 2 2+5 25 05 0.5 ZXCT1086 60V G = 50 Current Monitor 2.7 60 2.7 60 VS‐‐1 0.5 125 2 2+5 50 ZXCT1087 40V G = 50 Current Monitor 2.7 40 2.7 40 VS‐‐1 0.5 125 2 2+5 50 To find out more information: Family page – ZXCT1082/3 Family page – ZXCT1084/5/6/7 Datasheet SOT25 ‐40 to +125 X SOT25 X SOT25 0.2 X SOT25 0.2 X SOT25 http://www.diodes.com/products/catalog/list.php?parent-id=79 http://www.diodes.com/products/catalog/list.php?parent-id=78 http://www.diodes.com/datasheets/ZXCT1082_87.pdf O d i information Ordering i f ti Device Packaging Pack mark Reel size Tape width Quantity ZXCT1082E5TA SOT25 1082 7” 8mm 3000 ZXCT1083E5TA SOT25 1083 7” 8mm 3000 ZXCT1084E5TA SOT25 1084 7” 8mm 3000 ZXCT1085E5TA SOT25 1085 7” 8mm 3000 ZXCT1086E5TA SOT25 1086 7” 8mm 3000 ZXCT1087E5TA SOT25 1087 7” 8mm 3000 All variants are in packages that are “Green” Molding Compound (No Br, Sb) with Lead Free Finish/RoHS Compliant (Note 1) Notes:1.
