Table 5. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 6.0 V ≤ VPWR ≤ 20 V, 3.0 V ≤ VDD ≤ 5.5 V, -40 °C ≤ TA ≤ 125 °C, GND = 0 V, unless
otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless
otherwise noted.

32. Clock Fail detector available for PWM_en bit is set to logic [1] and CLOCK_sel is set to logic [0].
33. The PWM ratio is measured at VHS = 50% of VPWR 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 = 5.0 Ω resistive load.

34. Typical value guaranteed per design.
35. Value guaranteed per statistical analysis.
