This temperature increase is mainly caused by the total power dissipated by the integrated power MOSFET. To avoid any damage to the device when reaching high temperature, the ALED6000 implements a thermal shutdown feature: when the junction temperature reaches 170 °C (typ.) the device turns off the power MOSFET and shuts down. When the junction temperature drops to 155 °C (typ.), the device restarts with a new soft-start sequence. ALED6000 Overtemperature protection DS13018 - Rev 4 page 18/45 |
