NCV7428 fiche technique
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
