The Datasheet seems to state that if one of the circuits current-limit is exceeded, you can drive two circuits in parallel...
DS section 9.4.5 seems to state you would need 30~100nH inductance on each output in this case.
Could you provide more info on how to calculate the required inductance?
This driver IC when operating in Parallel, doesn't have an active current share; thus it seems like the Inductor's inductive reactance causes a current loop, and you multiply by this.
Is this understanding correct?
(I am so sorry if this translation is bad...there are some terms I am not familiar with)
Here, assuming there is some starting current in the motor during the tr/tf: 14ns time-frame listed in the DS,
the 30~100nH inductive reactance is used to help hold this back, but if so, then the calculated inductive reactance seems hard to estimate from the Driver IC side of the equation, and we're having a hard time coming up with a value to use...
Summary: How to properly calculate the required inductance on the outputs when using outputs in parallel for current sharing?
Is what I believe my customer is trying to ask.
