Figure 10. Self-start state machine

This state machine runs only if self-start option has been programmed.

5.6.7

Standby

The 80310 is in Standby mode if there is a LIN timeout, and in absence of alternator rotation (no phase), if power and reset (POR), or

with a LIN MID3C command, if nvm_lin_special is set.

• There is no excitation

• The duty cycle (DC) is equal to zero

The device needs a small amount of quiescent current to feed some functions such as oscillator. LIN timeout means:

• No activity on the LIN bus during a specified time

• or on a LIN watchdog timeout during a specified time
