STAT Output-Polarity Select. See Table 3 and the Status Outputs (STAT_) section.
On/Off Channel 2 Control Input. See the Mode section.
On/Off Channel 1 Control Input. See the Mode section.
Channel 1 Current-Limit Setting. Connect a resistor from LIM1 to GND to set current-trip
level. Connect to GND for the default 25mV threshold. Do not leave LIM1 unconnected.
Channel 1 Supply Input. Connect to a 1V to 15V supply voltage and to one end of R
Bypass with a 0.1µF capacitor to ground.
Channel 1 Current-Sense Input. Connect SENSE1 to the drain of an external MOSFET and
to one end of R
Channel 1 Gate-Drive Output. Connect to the gate of the external n-channel MOSFET.
