Comments
/ERR_OUT
Error output (open drain). Signals undervoltage or overcurrent. Tie to ENABLE for
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.
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
Reset of error flip-flop (active high). Clears error condition. The error condition should
at least be cleared once after IC power on.
at least be cleared once after IC power on.
ENABLE
Enables the power drivers (low: all MOSFETs become actively switched off)
