The 10-bit AFE53902-Q1 and 8-bit AFE43902-Q1 devices ( AFEx3902-Q1) are dual-channel, smart analog front ends (AFE) targeted for multislope thermal foldback of LED lighting. The output of LED lights reduce with an increase in temperature. Multislope thermal foldback helps maintain a steady light output from LEDs, irrespective of temperature change, while limiting the LED temperature to programmed thresholds.

The AFEx3902-Q1 have an ADC for temperature input and a DAC or PWM generator as an output. These devices have an integrated state machine that is preprogrammed as a multislope thermal foldback controller. The AFEx3902-Q1 are an excellent choice for thermal foldback of automotive rear lights and headlights, as well as horticulture lights. The AFEx3902-Q1 work independently from the parameters programed into the NVM, and thus enable these smart AFEs for processor-less applications and design reuse. These devices also automatically detect I 2C or SPI, and have an internal reference.
