DYNAMIC ELECTRICAL CHARACTERISTICS
Table 4. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 6.0V ≤ V_PWR ≤ 20V, 3.0V ≤ V_DD ≤ 5.5V, - 40°C ≤ T_A ≤ 125°C, GND = 0V, unless
otherwise noted. Typical values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions, unless
otherwise noted.

Notes
30. Clock Fail detector available for PWM_en bit is set to logic [1] and CLOCK_sel is set to logic [0].
31. The PWM ratio is measured at V_HS = 50% of V_PWR and for the default SR value. It is possible to put the device fully-on (PWM duty-cycle
100%) and fully-off (duty-cycle 0%). For values outside this range, a calibration is needed between the PWM duty-cycle programming
and the PWM on the output with R_L = 5.0Ω resistive load.
