Description
The MCP2025 provides a bidirectional, half-duplex
communication physical interface to meet the LIN bus
specification Revision 2.1 and SAE J2602-2. The
device incorporates a voltage regulator with 5V or 3.3V
70 mA regulated power supply output.
The device has been designed to meet the stringent
quiescent current requirements of the automotive
industry and will survive +43V load dump transients,
and double battery jumps.
MCP2025 family members include:
- MCP2025-500, 8-pin, LIN driver with 5.0V
regulator
- MCP2025-330, 8-pin, LIN driver with 3.3V
regulator
