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 V_OUT 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 V_S > ±8 kV
• These are Pb−Free Devices
