NCV7001 Quad Variable Reluctance Sensor Interface IC The NCV7001 is a four-channel variable reluctance sensor interface IC. Microprocessor control functions include two polarity 5.0 V programmable resets, two programmable watchdog inputs, and an enable function (OLE). Two watchdog inputs allow control from two independent microprocessors. Open sensor detection capability is provided. During test mode (NTEST = Low), a high on the OLE pin should provide a high on the output. A low under these conditions indicates an open load. This part has been designed to operate in an automotive environment. http://onsemi.com SO-24L DW SUFFIX CASE 751E 24 1 Features •Four Channel Capability •Differential Inputs •Open Sensor Detect •5.0 V Supply Operation with RESET and Watchdog Features •On-Chip Input Voltage Clamping •NCV Prefix for Automotive and Other Applications Requiring Site and Change Control •AEC Qualified •PPAP Capable •Pb-Free Packages are Available* MARKING DIAGRAM 24 NCV7001 AWLYYWWG 1 A WL YY WW G = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package PIN CONNECTIONS Typical Applications •Antilock Braking Systems (ABS) •Traction Control Systems (TCS) •Vehicle Dynamics Control (VDC) RDLY NTEST INN1 INP1 INN2 INP2 INP3 INN3 INP4 INN4 THOLD GND 1 24 NOUT1 NOUT2 WDO LVI NLVI WD2 VCC WD1 OLE WDLY NOUT3 NOUT4 ORDERING INFORMATION Device NCV7001DW NCV7001DWG NCV7001DWR2 NCV7001DWR2G *For additional information on our Pb-Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. © Semiconductor Components Industries, LLC, 2007 October, 2007 - Rev. 4 1 Package Shipping† SO-24L 30 Units/Rail SO-24L (Pb-Free) 30 Units/Rail SO-24L 1000 Tape & Reel SO-24L (Pb-Free) 1000 Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D.
