DEAD TIME
To protect the device against simultaneous conduction in both arms of the bridge and the resulting rail-to-
rail short, the logic circuits provide a dead time.
THERMAL PROTECTION
A thermal protection circuit has been included that will disable the device if the junction temperature reach-
es 150 °C. When the temperature has fallen to a safe level the device restarts under the control of the
input and enable signals.
