3 Description
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
I2C or SPI, and have an internal reference.
