Description
The ALED7707 device consists of an automotive
grade (AEC Q100 compliant) monolithic boost
converter and six controlled current generators
(rows) specifically designed to supply LED arrays
used in the backlighting of LCD panels. The
device can manage an output voltage up to 36 V
(i.e.: 10 white LEDs per row).
The generators can be externally programmed to
sink up to 85 mA and can be dimmed via a PWM
signal (1 dimming duty cycle at 1 kHz can be
managed). The device allows to detect and
manage the open and shorted LED faults and to
let unused rows floating. Basic protections (output
overvoltage, internal MOSFET overcurrent and
thermal shutdown) are provided.
Features

? Backlight driver section
– Six rows with 85 mA maximum current
capability (adjustable)
– Rows disable option
– Less than 10 μs minimum dimming on-time
– ± 3 current matching between rows
– LED failure (open and short-circuit)
detection
Applications
? Infotainment LCD backlight
? Daytime running lights
? Car interior/exterior lights
? Dashboard backlight
