Notes

36. In Direct Input mode, the lower frequency limit is 0 Hz with RSTB=5.0 V and 4.0 Hz with RSTB=0V. Duty-cycle applies to instants at which

VHS = 50 % VPWR. For low duty-cycle values, the effective value also depends on the value of the selected slew rate.

37. Actually, the device can be operated outside the specified duty cycle and frequency ranges (basic protective functions OC, SC, UV, OV,

OT remain active) but the availability of the diagnostic functions OL_ON, OL_OFF, OS is affected.

38. Values guaranteed from 60 Hz to 1.0 kHz (recommended switching frequency range for internal clock operation).
