80310

5.6.8

Wake-up

This state is reached when an edge is detected on the phase (Phase voltage > Phase sensitivity)

• The logic is out of reset

• All the blocks are on

• There is no regulation. DC=0%

5.6.9

Excitation 100% DC

When the speed has reached Start_aa, then the device goes into this state until the high phase appears, or during a 100 ms maximum.

• The logic is out of reset.

• All the blocks are on.

• There is no regulation. DC = 100%

Start_aa (see Table 1): is a special threshold for the self-start when it is in Wake-up mode, before going in EXC 100% DC, waiting for high

phase. Once high phase appeared the state machine is exactly the same as with LIN wake-up. Start_aa can be programmed at 3000 rpm

or 4000 rpm.

5.6.10 Regulation with LRC

In this mode, the 80310 regulates the alternator output to the set reference level. The excitation is controlled by LRC, if B+A is lower than

into regulation without LRC.

5.6.11 Regulation without LRC

goes below the phase stop regulating RPM, the device goes to Pre-excitation mode.

5.6.12 Re-regulation:

back to the regulation mode, with or without LRC.

5.6.13 LIN bus information

The operational control and programming, required in the end application, is carried out through the LIN interface. Refer to Tables 7 to

15. The regulator shall only give pre-excitation when it receives a LIN command targeted for it, the shutdown command is the code that

would otherwise set 10.6 V (“000000”). LIN addresses are listed in MID format, Table 8, while the data fields are listed in [MSB:LSB] format
