The LED backlight driver is a key part of this LCD panel system and some engineers may encounter various problems when choosing the right devices and designing such circuits. These LED drivers regulate the output current to the LED’s on the panel. In automotive environments the LED’s on the display panel can get very hot. Temperature sensors are often used to monitor the LED temperature and provide brightness regulation. Additionally, temperature sensors are also used to monitor the LED Driver thermals. With the remote thermistor embedded in the backlight enclosure/panel there are a couple ways to achieve thermal sensing and foldback with an LED Driver. The integrated thermistor can be used with the foldback pin of an LED Driver or provide thermal foldback in a discrete implementation to the LED Driver. This application report shows how to implement TI’s TMP6 family of thermistors with TI’s LP886x family of low EMI Automotive LED Drivers, specifically the LP8867-Q1.
