Comments
Error output (open drain). Signals undervoltage or overcurrent. Tie to ENABLE for
/ERR_OUT
direct self protection of the driver. The internal error condition generator has a higher
priority than the CLR_ERR input, i.e. the error condition can not be cleared, as long as
it is persistent.
CLR_ERR
ENABLE
Reset of error flip-flop (active high). Clears error condition. The error condition should
at least be cleared once after IC power on.
Enables the power drivers (low: all MOSFETs become actively switched off)
