The behaviour of Hardware Error handling is described in following table.
Hardware Error
HE
Behaviour when
device
power on
Behaviour when
Line Enable=1
SV=0 (standard mode)
Short to GND
(high side over
current)
Iq out of range
(Satellite quiescent
current above upper
limit)
Over Temperature
mask when channel is
deactivated
mask when channel is
deactivated
mask when channel is
deactivated
External resistor out
of range
No CLK
VBUS/VSYNC too

The behaviour of Over Current Error handling is described in following table.
Over current Error
OE
Behaviour when

Behaviour when
Line Enable=1
SV=0 (standard mode)
Short to V+
(low side over
current)
mask when channel is
deactivated
• mask for 5.12 ms after
channel activation
• 512 µs debouncing
Behaviour when
Line Enable=1
SV=1 (increased/daisy
chain mode)
• mask for 10.24 ms after
channel activation
• 512 µs debouncing
HE and OE are reset with external or internal reset or SPI_LINE_ENABLE command with LEx=0 (OFF) for the
affected channel. V_Sync and V_Bus error can be active some seconds after power on and a HE is set without
any channel is activated. To activate a channel in this case first the HE must be reset with the
SPI_LINE_ENABLE command with LEx=0 (OFF).
