(1) All electrical characteristics having room temperature limits are tested during production with T_A = T_J = 25°C. All hot and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control.

(2) The V_CC output is intended as a self bias for the internal gate drive power and control circuits. Device thermal limitations limit external loading.

(3) For devices in the WSON-8 package, the MOSFET R_DS(on) limits are specified by design characterization data only.
