TYPICAL PERFORMANCE CHARACTERISTICS
SENSE
comparator. Built-in offsets between the SENSE
pins in conjunction with R
olds. Do not pull this pin more than 15V below V
than 0.3V below ground.
I
sation Point and Run Control Inputs. The current com-
parator threshold increases with this control voltage.
Nominal voltage range for this pin is 1.19V to 2.4V. Forcing
this pin below 0.8V causes the device to be shut down. In
