TIMING, PROTECTION AND CONTROL
t_{pd,R_GATE-OP}
Start up time, from EN_GATE active high
to device ready for normal operation
PVDD is up before start up, all charge
pump caps and regulator caps as in
recommended condition
t_{pd,R_GATE-Quick}
If EN_GATE goes from high to low and
back to high state within quick reset time,
it will only reset all faults and gate driver
without powering down charge pump,
current amp, and related internal voltage
regulators.

(1) Dead time programming definition: Adjustable delay from GH_x falling edge to GL_X rising edge, and GL_X falling edge to GH_X rising
edge. This is a minimum dead-time insertion. It is not added to the value set by the microcontroller externally.
