PROTECTION AND DIAGNOSIS FEATURES
PROTECTION AND DIAGNOSIS FEATURES
FAULT DETECTION
General Notes
All fault reporting passes through a 400 ms digital filter to
avoid false indication problems, and transition from one fault
type to another should be “clean”.
MECHANICAL FAULT (F_MEC)
The Phase is off (Low Phase RPM below stop_regulation
threshold). Reported in Alternator A/B read data field (ID=11,
13), byte 1.
ELECTRICAL FAULT (F_EL)
If one of these faults appear:
The number of “1”s in all the OTP bits, NVM[80:1] is not
ODD. The parity bit is included in the calculation
The Phase is on (Low Phase RPM above
stop_regulation threshold) but High Phase 1 is not
detected
B+A reaches 16.5 V with EXC at 100% DC
Short circuit excitation load
B+A stays at 75% of the target voltage when LRC is off
Note: This 5th additional condition is enabled only when
the NVM bit “Low Voltage Threshold” is enabled. Reported in
Alternator A/B read data field (ID=11, 13), byte 1.
ELECTRICAL FAULT (HP MASK)
A fault detection when High phase signal is cut is reported
on the electrical fault.
Option (OTP) available to remove this fault detection.
THERMAL FAULT (F_HT)
A thermal fault is reported when the die temperature
exceeds the programmed threshold. Reported in Alternator
A/B read data field (ID=11, 13), byte 1.
The programmed threshold in hexadecimal corresponds
to the following temperature in degrees:
6'b110010;//135degres
6'b110100;//145degres
6'b110110;//150degres
6'b111001;//160degres
ADDITIONAL ERRORS
LIN Bus Timeout
Check two timeouts:
Activity on RXD is below 3 or 8 seconds (depending on
the OTP bit)
Time between two consecutive valid messages is below
3 or 8 seconds (depending on the OTP bit)
This flag is reset once the microcontroller sends MID 11 for
ALTA, or MID 13 for Alt B. Reported in Alternator A/B read
data field (ID=11, 13), byte 2.
Comm Error
Checks the ID parity bits + Checksum byte + (TXD = RXD
when responding) + LIN Physical layout not in over-current
limitation. Reported in Alternator A/B read data field (ID=11,
13), byte 2.
LIN protocol errors:
Sync Break Error: This flag is up when Synchro break
Field duration is lower than 10Tbits.
Identifier parity Error: Comm error flag also reported in
MID11
Checksum Error: Comm error flag also reported in
MID11
Slave not responding Error: Tframe Max exceeded (LIN
Specification revision 1.3).
These flags are reset once the microcontroller sends MID
12 for ALTA, or MID 14 for Alt B. Reported in Alternator A/B
read data field (ID=12, 14), byte 2.
