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
at 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.
The MCP2025 family members include:
- MCP2025-500, 8-pin, LIN driver with 5.0V
regulator
- MCP2025-330, 8-pin, LIN driver with 3.3V
regulator
