EEPROM-Programmable, High-Voltage,
350mA LED Drivers with LED Current Foldback
General Description
The MAX16805/MAX16806 LED drivers eliminate the
need for microcontrollers or switch-mode converters for
automotive interior dome, map, and courtesy light
applications. An EEPROM-programmable LED current-
sense reference simplifies production by using one
sense resistor to set the LED current for all LED bins. A

LED Current Thermal Foldback (MAX16806)
? On-Board 200Hz Ramp Generator Eliminates the
Need for μC PWM Signal
dual-mode DIM pin and an on-board 200Hz ramp gen-
erator allow for PWM dimming with an analog or PWM
control signal. The analog control signal at dimming
input DIM allows for the “theater dimming” effect to be
implemented. Fast turn-on/-off times ensure a wide-
range PWM operation, while waveshaping circuitry min-
imizes EMI. EEPROM-programmable LED current
foldback makes it possible to operate at a high input
voltage, while saving the cost and space associated
with having a large heatsink. The MAX16806 works with
an external thermal sensor to maintain maximum LED
junction temperature by folding back the LED current.
The thermal foldback temperature knee and slope are
EEPROM programmable. The MAX16806 SW pin sup-
