voltage. [Vil Max = 1.5V, Vih Min = 3.6V]
Supply input voltage: there is an internal clamp [Typ. 15.6V]
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.
The pin has not be pulled through a low impedance to V
CC
, because of the drop on the
current source that feeds Rdt. The operative range is: Vdt....270K
