Operation is specified for internal (junction temperature) up to 150 °C. Self-heating due to internal power

dissipation should be considered for each application. Maximum junction temperature is internally limited by the

thermal shut-down circuit which disables the driver outputs when the junction temperature reaches 165 °C.
