H bridge output waveform??

[fahd]

Hi buddies
i am having a problem with my H bridge IC (MSK 4200) output waveform.
i am having a sawtooth wave at the output terminals of the IC instead of pulses. ouput also have no effect if i change the input voltage to the mosfets. i donot know what kind of waveform it is and where i am wrong...plzzzzzzzz help

Schematics please. What do you have connected at the H-bridge output. What exactly is your input to the H-bridge? Are you measuring the output with the load connected? What is the output without load?

i have connected a 10K resistor at the output and rest of the information is available in the data sheet for MSK 4200

**broken link removed**

i havenot connected the feedback circuit for the current control......There z no change with and without output load..

Rsens A and B need to be grounded if you are not using current sense.
