Note 1: “x” in front of a pin name refers to either A, B or C phase. (e.g. xHI can be either AHI, BHI or CHI).
2: Specification for packaged product only.
3: V_IL(MAX) = maximum positive voltage applied to the input which will be accepted by the device as a logic
low.
V_IH(MIN) = minimum positive voltage applied to the input which will be accepted by the device as a logic
high.
4: Guaranteed by design. Not production tested.
