SNVSCC4 October 2023 LP5811
PRODUCTION DATA
The LED driver of LP5811 goes into thermal shutdown state once the junction temperature exceeds 150°C. All LEDs turn off to avoid damaging the device. When the junction temperature drops below the thermal shutdown recovery temperature 130°C, the LED driver starts operating again.
The boost converter of LP5811 stops switching and is shutdown once the junction temperature exceeds 155°C, and the power on reset of the LED driver part is also triggered. When the junction temperature drops below the thermal shutdown recovery temperature, typically 130°C, the LP5811 enters shutdown state, and then the device needs to be configured again for normal operations.
