FAQ
Q: What is a System Basis Chip (SBC)?
A: A System Basis Chip integrates multiple functions required in automotive applications, such as voltage regulation, CAN transceivers, and system monitoring, into a single package. This reduces component count and board space compared to discrete implementations.
Q: What voltage outputs does the TEF80x provide?
A: The TEF80x provides configurable 5V and 3.3V outputs, typically capable of sourcing up to 150mA each, suitable for powering microcontrollers and other digital circuits in automotive applications.
Q: What protection features are included?
A: The TEF80x includes over-voltage protection (OVP), under-voltage lockout (UVLO), thermal shutdown, and short-circuit protection to ensure robust operation in harsh automotive environments.
Q: Can the TEF80x operate in automotive sleep modes?
A: Yes, the TEF80x is designed with very low standby current (typically <100 µA) to support automotive sleep modes and reduce power consumption when the vehicle is off.
Design Considerations
When implementing the TEF80x in your design, consider:
- Input Filtering: Proper input capacitor selection for EMI performance
- Thermal Management: Adequate copper area for heat dissipation
- EMC Compliance: Layout guidelines for automotive EMC requirements
