Positioning data and diagnostic data are reset if they have been successfully transferred to the μC and have been
acknowledged by the μC. Acknowledge is performed by setting the Acknowledge bit (no. 13) to 1
Pending error conditions like overtemperature prevent resetting of DRB signal even after acknowledge.
If a command is sent from the μC to activate an output that has been shut off, but diagnostic data has not yet
been acknowledged, the command will be ignored and DRB is activated again. It is possible to reactivate any out-
put OUTx with the same telegram that contains the acknowledge.
5.2.17 standby Mode
Sending standby command to the IC switches the device into standby mode. All half bridge outputs are turned
into tristate mode, charge pump and oscillator are switched off, and current consumption in the VBAT_HV supply
is reduced to a value of I
and consumes a standby current IDD,STBY.
Sending a standby command while a motor is running sets the motor into break mode, i.e. both low side drivers
are turned on. Ripples are counted until the motor has stopped, and DRB becomes zero. After a timeout of 100ms
standby mode is activated, if in the meantime the μC did not initialise any other activity.
It takes a data telegram other than the standby or soft reset command to get back to normal operation. A delay of
t
After leaving the standby mode all half bridges stay in tristate mode, unless they get a activating command from
the μC.
After power on, the IC starts in standby mode.
5.2.18 software reset
The μC can reset all registers of the chip by sending a Software Reset command. It contains address 111
Switch bit 1
ters. Reset signal remains until the next rising edge of CSB.
A software reset has the same effect as a power on reset due to the fact that both reset methods trigger the same
reset generator (see. chapter 5.2.1).
5.2.19 acknowledge
All data (diagnostic information or position data) indicated by an active DRB output have to be acknowledged by
the μC. The IC stores the information, and even though the over-current or overtemperature condition may no
longer be present, all data is available until reset by acknowledge.
Acknowledging the position of a motor allows the μC to send new positioning data for the same motor with the
same SPI protocol.
If there is no position data available in the IC, in the case of a data transmission to the μC the address is 000
the position data is undefined (random).
