6.5 Electrical Characteristics

Typical limits are for T_J = 25°C only, and all maximum and minimum limits apply over the junction temperature (T_J) range of –40°C to +125°C. Minimum and maximum limits are specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference purposes only. Unless otherwise stated, the following conditions apply: V_IN = 48 V and R_ON = 200 kΩ.⁽¹⁾.

(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 procured in the WSON-8 package, the Rds(on) limits are specified by design characterization data only.
