¹Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions. Performance may vary for individual units, within

the specified maximum and minimum limits.

²Negative current is defined as coming out of (sourcing from) the specified device pin.

³Operation at a step frequency greater than the specified minimum value is possible but not warranteed.

⁴E_G= ([V_REF/8] – V_SENSE)/(V_REF/8).
