Note 4:
All devices are production tested at +25°C. Limits over temperature are guaranteed by design.
Threshold is reached when charge pump turns off.
Gate discharge current is guaranteed through the testing of gate fall time.
V IN switchover threshold is V IN at which the gate-drive voltage (V GATE - V IN ) goes from 5V to 7V, V IN rising and (V IN ≥ V BUS ).
