Time period required for current to change from 10% to 90% of it’s value.
Chopping settling time is the required time to have valid device output after power up of the device.
Crossover dead time is a time period during which all output transistors are switched off.
Restart delay is a time period during which only one pair of the output transistors is switched on.
