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 lowâvoltage power supply for
the application microcontroller and other loads and includes a LIN
transceiver.
Features
⢠Control Logic
⦠Ensures safe powerâup 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
Lowâdrop Voltage Regulator
⦠Can deliver up to 70 mA with accuracy of ±2%
⦠Supplies typically the ECUâs 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; AECâQ100
Qualified and PPAP Capable
⢠These Devices are PbâFree, Halogen Free/BFR Free and are RoHS
Compliant
Typical Applications
⢠Automotive
⢠Industrial Networks
