NCV7428D15R2G

The voltage regulator in the NCV7428 System Basis Chip can deliver up to 70 mA with an accuracy of ±2%. It supplies typically the ECU's microcontroller and includes an undervoltage detector with a reset output to the supplied microcontroller. An external capacitor needs to be connected to the VOUT pin for stability and to filter disturbances caused by connected loads. All low-voltage digital pins are related to VOUT.

The NCV7428 System Basis Chip integrates functions typically found in automotive Electronic Control Units (ECUs) such as control logic for safe power-up sequence, mode transitions, and generating reset signals, a 3.3 V or 5 V VOUT supply from a low-drop voltage regulator delivering up to 70 mA with ±2% accuracy, LIN transceiver compliant with LIN2.x and J2602 standards, undervoltage detector with reset output, thermal shutdown protection, load dump protection, LIN bus pin protection against transients, ESD protection, and a wettable flank package for enhanced optical inspection quality.
