High-side H
・When under-voltage (5.5V typ.) is detected, only FAULT outputs “H".
・When a in-phase high side and the low side input are the “H" levels, all
Low-side H
Neither the output nor the operation of the charge pump circuit stops(off).
the outputs be made “L" level, and the “H" level is output to FAULT.

High-side/low-side arm shorting mode is disabled by the internal logic. All outputs can be turned off. The
deadtime of this product is 1μs. That doesn't contain deadtime of external power MOSFET. Please set the
deadtime of the input signal after considering the switching time of external power MOSFET.
By the oscillation signal from the outside to C
method, please input the signal to C
