Who We Are Management. DMOS full bridge driver. Extracts from L data sheet: Although the device guarantees the absence of cross-conduction, the presence of the intrinsic diodes in the POWER DMOS structure causes the generation of current spikes on the sensing terminals. Each channel half-bridge of the device is controlled by a separate logic input, while a common enable controls both channels. L H-bridge output current rings in response to step input Ask Question.

Support Home Video Center. Selectors Simulators and Models. Product is in design feasibility stage. Cloud Components and Bridgf. The DMOS output transistors can operate at supply voltages up to 42V and efficiently at high switching speeds.

Below is an oscillation at the rising edge: Can you show us the current waveform over a complete PWM cycle? Reducing torque variation in half step drive.

Although the device guarantees the absence of cross-conduction, the presence of the intrinsic diodes in the POWER DMOS structure causes the generation of current spikes on the sensing terminals.

ST Code of Conduct Blog. Product is in design stage Target: Not Recommended for New Design.

I’m guessing it doesn’t help that I’m using a breadboard and my wires aren’t the cleanest see edits. However, I’m confused that l203 amplitude would change with the duty cycle, almost in an anticipatory way.

Limited Engineering samples available Preview: No availability reported, please contact our Sales office. I briidge 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.

Communications Equipment, Computers and Peripherals. I have a uF capacitor right next to the power supply connection, and a 15uF across the supply pins to the IC.

I’ll be hooking this into a microcontroller ADC, and that -6V spike looks very unfriendly. Computers and Peripherals Data Center. 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 the L ends.

They grew with duty cycle and were also consistent between cycles. Andy aka k 10 When the output switches from high to low, a current spike is generated associated with the capacitor C1.

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.
