DC CHARACTERISTICS (Note 1, 2) (CONTINUED)

Electrical Characteristics:

Unless otherwise indicated, VDD = VxHB = 12V; VEN = 5V; VSS = VHS = 0V; No load on

xLO or xHO; TA = 25°C; unless noted. Bold values indicate –40°C< TJ < +125°C.

Conditions

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).

Specification for packaged product only.

VIL(MAX) = maximum positive voltage applied to the input which will be accepted by the device as a logic

low.

VIH(MIN) = minimum positive voltage applied to the input which will be accepted by the device as a logic

high.

Guaranteed by design. Not production tested.
