Application's Precautions

(1) External heatsink is needed when used. External heatsink should be fixed to the chassis.

(2) Fin of the IC can be connected to GND.

(3) Please prevent Output to Vcc short, Output to GND short, Pin shift and Load short, The IC may be damaged if any of these occurs and smoke may be observed.

(4) The temperature protection circuit will operate at Tj around 150ºC.

However, if temperature decrease, the protection decrease, the protection circuit will automatically be deactivated and resume normal operatin.

(5) The Absolute Maximum Supply Voltage for this IC is soecified as 26V. The IC is permitted to operate up to theis voltage, without causing damagem, for the condition that no signal is applied to all the 2 input pins.

(6) For the condition of chip junction temperature below the minimum thermal shutdown temperature, under continuous operation, this will not cause damahe to the IC for the recommended application. The minimum thermal shutdown temperature of this IC is typically 140˚C. This valus is provided as a design reference and is not guaranteed by testing.
