Where are the power supply bypass capacitors? Support Home Video Center. On the low-to-high transition a spike of the same polarity is generated by C2, preceded by a spike of the opposite polarity due to the charging of the input capacity of the lower POWER DMOS transistor fig. Below is an oscillation at the rising edge: Home Questions Tags Users Unanswered. I’ll add some decoupling capacitors near the chip and grab pictures over the whole cycle tomorrow. Andy aka k 10

Where are the power supply bypass capacitors?

Who We Are Management. Product is in volume production only to support customers ongoing production.

Andy aka k 10 Compare to the signal over a whole pulse: The DMOS output transistors can operate at supply voltages up to 42V and efficiently at high switching speeds. They grew with duty cycle and were also consistent between cycles. Product is in volume production Evaluation: No commitment taken to produce Proposal: Support Home Video Center.

When I looked at the sense resistor voltage on a scope, I noticed huge artifacts right on both the rising and falling edge of the PWM waveform. Below is an oscillation at the rising edge:. I have a hunch that this is a byproduct of the bootstrap capacitors interacting with the motor windings, because the ringing reminds me of an RLC oscillator.

I suspect that it has something to do with the charge differences on the capacitor leftover from the last cycle, but that’s beyond my understanding of l62203 L ends. Whoa, I had no idea it was so sensitive to the probe setup. Can you show us the current waveform over a complete PWM cycle?
