Power supply fail

Overvoltage and undervoltage detection on VS

4.1

VS overvoltage

If the supply voltage Vs reaches the overvoltage threshold (VSOV)

●

The outputs OUT1,2, REL1,2 and LIN are switched to high impedance state (load

protection).

●

The overvoltage bit is set and can be cleared with a ‘Read and Clear’ command.

●

Outputs REL1,2 can be excluded from a shutdown in case of overvoltage by SPI

4.2

VS undervoltage

If the supply voltage Vs drops below the undervoltage threshold voltage (VSUV)

●

The outputs OUT1,2, REL1,2, LIN are switched to high impedance state.

●

The undervoltage bit is set and can be cleared with the ‘Read and Clear’ command.

●

Outputs REL1,2 can be excluded from a shutdown in case of undervoltage by SPI

●

Output OUT1,2 can be excluded from a shutdown in case of undervoltage by SPI
