QFN
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 V
BAT
to the range of V
REG
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.
