The MC33981 can work down (~100Hz). The fault management reset can not be guaranteed with PWM frequency lower than 5kHz
(INHS=0 during 200us typ)
Values for CBOOT=100nF. Refer to the paragraph entitled
production tested.
Turn-ON delay time measured from rising edge of INHS that turns the output ON to V
Turn-OFF delay time measured from falling edge of INHS that turns the output OFF to V
The ratio is measured at V
