Thermal shutdown function The thermal shutdown circuit is incorporated and the output is turned off when junction temperature Tj exceeds 180°C . As the temperature falls by hysteresis, the output turned on again (automatic restoration). The thermal shutdown circuit does not guarantee the protection of the final product because it operates when the temperature exceed the junction temperature of Tjmax=150°C.
