To prevent an undesired wake-up scenario in a LIN bus
loss situation, the Power-Down mode has to be entered
via the Transmitter-Off mode observing specific timings
and the switching sequence outlined below (“Forced
Power-Down mode”).
The following state machine diagram shows the paths
to enter the MCP2003 Power-Down mode from
Operation mode or Transmitter-Off mode.
FIGURE 2:
The Forced Power-Down mode sequence is used to
enter Power-Down mode without activating the
transceiver to reduce the current consumption of the
transceiver. After the device is in Ready mode, this path
could be selected by holding TXD and CS in low state
for t
before resetting CS to ‘0’. This results in all functionality
being disabled in the transceiver until CS goes high or
a falling edge on LIN bus had been detected.

To enter Power-Down mode from Ready mode, the
MCP2003 has two different paths:
• Passing through Transmitter-Off mode (T
