NCV7428

NCV7428 System Basis Chip with Integrated LIN and Voltage Regulator Description NCV7428 is a System Basis Chip (SBC) integrating functions typically found in automotive Electronic Control Units (ECUs). NCV7428 provides and monitors the low−voltage power supply for the application microcontroller and other loads and includes a LIN transceiver. Features Control Logic ♦ Ensures safe power−up sequence and the correct reaction to different supply conditions ♦ Controls mode transitions including the power management and bus wakeup treatment ♦ Generates reset 3.3 V or 5 V VOUT Supply depending on the Version from a Low−drop Voltage Regulator ♦ Can deliver up to 70 mA with accuracy of ±2% ♦ Supplies typically the ECU’s microcontroller ♦ Undervoltage detector with a reset output to the supplied microcontroller LIN Transceiver ♦ LIN2.x and J2602 compliant ♦ TxD dominant timeout protection ♦ Transceiver mode controlled by dedicated input pin Protection and Monitoring Functions ♦ Thermal shutdown protection ♦ Load dump protection (45 V) ♦ LIN Bus pin protected against transients in an automotive environment ♦ ESD protection level for LIN and VS > ±8 kV Wettable Flank Package for Enhanced Optical Inspection Quality NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applications Automotive Industrial Netw...
