1.5.8
Digital Input Interface and Dead Time Generator.
Note 1: INA will override INB and tPW is reduced by tINDEAD when INA overlaps INB.
Note 2: The formula for tINDEAD is 2000*CA or 2000*CB (CA or CB is the capacitor value in Farads). Example
2000*200e-12 = 400nS. The maximum value of tINDEAD is only limited by the application
1.5.9
External Clock and Internal Oscillator
To protect power converter switches, the power converter shuts down if the external converter clock (CLK) is high for
greater than tDOG_OSC (40s). The power converter will remain shut down until eight valid clocks are received.

Specifications are characterized and guaranteed by design. All units are not production tested.
