Part Number: TIDM-02013 This image shows the PWM waveforms of the two lower arms on the secondary side. Is this duty cycle normal? Why is the duty cycle in the code multiplied by 2? From the observation of the waveforms, it seems more like the duty cycle…
Hi, guohaoyue
The lead-off detection principle is described in the Datasheet 9.3.2.4.3 Lead-Off Detection section.
The basic principle is to inject an excitation current and measure the voltage to determine if the electrode is off. As shown in the lead…
