Description
The MCP2050 provides a bidirectional, half-duplex
communication physical interface to meet the LIN bus
specification Revision 2.1 and SAE J2602. The device
incorporates a voltage regulator with 5V or 3.3V 70 mA
regulated power supply output. The on-chip WWDT
allows users to adjust the size of the reset window by
using an external resistor. The ratiometric VBAT pin
scales down VBAT to the range of VREG so it can be
monitored by an A/D converter.
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.
