Non-Overlapping LI/HI Input Mode

(MIC4607-1)

In non-overlapping LI/HI input mode, enough delay is

added between the xLI and xHI inputs to allow xHS to

be low before xLI is pulled high and similarly xLO is low

before xHI goes high.

xHO goes high with a high signal on xHI after a typical

delay of 35 ns (tHPLH). xHI going low drives xHO low

also with typical delay of 35 ns (tHPHL).

Likewise, xLI going high forces xLO high after typical

delay of 35 ns (tLPLH) and xLO follows low transition of

xLI after typical delay of 35 ns (tLPHL).

xHO and xLO output rise and fall times (tR/tF) are typi-

cally 20 ns driving 1000 pF capacitive loads.

Note 1:

All propagation delays are measured from the 50% voltage level and rise/fall times are measured 10% to

90%.

“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).
