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.
