Doc ID 13518 Rev 5
3
Protection and diagnosis
3.1
Power supply fail
Over and under-voltage detection on Vs.
3.1.1
Over voltage
If the supply voltage Vs reaches the over voltage threshold (VSOV)
●
The outputs HS1..4, OUT_HS, Rel1,2, and LIN are switched to high impedance state
(load protection)
●
The over voltage bit is set and can be cleared with the clear bit (CR1,CLR)
●
Automatic recovery after Vs over-voltage; selectable via SPI (CR2, bit4)
3.1.2
Under voltage
If the supply voltage Vs drops below the under voltage threshold voltage(VSUV)
●
The outputs HS1..4, OUTHS, Rel1,2, and LIN are switched to high impedance state
(load protection)
●
The under voltage bit is set
●
Automatic recovery after Vs under-voltage; selectable via SPI (CR2, bit4)
3.2
Temperature warning and thermal shutdown
See state chart: “ Protection and diagnosis”.
3.3
SPI diagnosis
Digital diagnosis features are provided by SPI:
●
V1 reset threshold programmable
●
Over temperature including pre warning
●
Open load separately for each output stage
●
Overload status
●
Vs-supply over/under voltage
●
V1 and V2 fail bit
●
Status of the WU1...4, LIN and INH pin
●
Cold start bit
●
Number of unsuccessful V1 restarts after thermal shutdown
●
Number of sequential watchdog failures
●
Status of watchdog trigger bit TRIG: (SR1, Bit 16)
●
LIN status (short to ground, short to VBAT, dominant TxD)
See the following state chart: “Protection and diagnosis”.
