TPS22919-Q1 Typical Application.jpg
1. Rise and fall times of the control signal are 100 ns
2. Turn-off times and fall times are dependent on the time constant at the load. For the TPS22919-Q1 devices, the internal pull-down resistance QOD is enabled when the switch is disabled. The time constant is (RQOD + RPD,QOD || RL) × CL.
