6.3.4.1 TPS28225 3-State Exit Mode
- To exit the 3-state operation mode, the PWM signal should go low and then high at least once.
This is necessary to restore the voltage across the bootstrap capacitor that could be discharged during the 3-state mode if the 3-state condition lasts long enough.
Figure 6-2 6-V Amplitude PWM Pulse
Figure 6-3 2.5-V Amplitude PWM PulseNote:
The driver sets UGATE low and LGATE high when PWM is low. When the PWM goes high, UGATE goes high and LGATE goes low.
