I

High impedance pin with two functionalities. When pulled lower than Vdt [Typ. 0.5V] the

device is shut down. A voltage higher than Vdt sets the dead time between high side gate

driver and low side gate driver. The dead time value can be set forcing a certain voltage

level on the pin or connecting a resistor between pin 3 and ground.

Care must be taken to avoid below threshold spikes on pin 3 that can cause undesired

shut down of the IC. For this reason the connection of the components between pin 3 and

ground has to be as short as possible. This pin can not be left floating for the same reason.
