Notes
36. Clock Fail detector available for PWM_en bit is set to logic [1] and CLOCK_sel is set to logic [0].
37. 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
= 5.0 Ohm resistive load.
38. Typical value guaranteed per design.
39. Value guaranteed per statistical analysis.
