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

Definitions
The characteristics defined in this section are guaranteed within the operating ranges listed in Table 4, unless stated
otherwise. All voltages are referenced to GND (Pin 3). Positive currents flow into the respective pin.
Table 6. DC CHARACTERISTICS (VS = 5.5 V to 28 V; TJ = −40°C to +150°C; Bus Load = 500 W (VS to LIN); unless otherwise
specified. Typical values are given at VS = 12 V and TJ = 25°C, unless otherwise specified.)

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
6. In case LIN bus capacitor of at least 82 pF is not used VOUT_5_EMC and VOUT_33_EMC needs to be taken into account.
7. Tested according to: LIN Conformance Test Specification Package for LIN 2.1, October 10th, 2008. Verified by external test house.
8. Values based on design and characterization. Not tested in production.
9. In parallel with this capacitor any other capacitor can be placed with no limit to ESR and capacitance value
10. The voltage drop in Normal mode between LIN and VS pin is the sum of the diode drop and the drop at serial pull−up resistor. The drop
at the switch is negligible. See Figure 1.
