NCV7361A
FUNCTIONAL DESCRIPTION
The NCV7361A consists of a low drop voltage regulator
5.0 V/50 mA and a LIN Bus transceiver, which is a
bidirectional bus interface for data transfer between the
LIN bus and the LIN protocol controller.
Additionally, the NCV7361A features a RESET output
with a reset delay of 100 ms and a fixed threshold of 4.65 V
and Enable (EN) control for the regulator.
Operating Modes
The NCV7361A provides two main operating modes
“normal” and “sleep” and the intermediate states “POR”,
“Ini−state” and “thermal shutdown”. The main modes are
fixed states defined by basic actions (VSUP start, EN or
wake−up). The intermediate states are soft states. They
aren’t defined by logical actions but by changes of voltage
(VSUP, VOUT) or junction temperature.

Figure 15. State Diagram of Operating Modes
Normal Mode
The whole NCV7361A is active. Switching to normal
mode can be done via the following actions:
• Start of VSUP or after Undervoltage Reset
• Rising Edge at EN (EN = High) (Local Wake−Up)
• Activity on the LIN Bus (Remote Wake−Up)
Sleep Mode
Sleep mode is most current saving. With a falling edge
on EN (EN = Low) the NCV7361A is switched from
normal mode into sleep mode. The voltage regulator will
be switched off and the LIN transceiver is in
recessive state.
