AL5816Q
AUTOMOTIVE COMPLIANT 60V LINEAR LED CONTROLLER
Description
Pin Assignments
The AL5816Q is a 5-terminal adjustable constant current linear LED
controller offering excellent temperature stability and current
capability. The AL5816Q can work with a wide input voltage range
from 4.5V to 60V. With its low 200mV current sense FB voltage, it
controls the regulation of LED current with minimum power dissipation
compared with traditional linear LED drivers. This makes it ideal for
medium to high current LEDs.

PWM 1
GND 2
The device has an internal output drive up to 15mA, which enables it
to drive external Bipolar transistors or MOSFETs. It also provides the
capability to drive longer LED chains with low drop out voltage and
multiple LED channels.
The AL5816Q has LED current adjusted and controlled by a sense
resistor connected across FB pin and GND. The voltage across this
resistor is controlled to a precise 0.2V thus controlling the current.
The AL5816Q can be dimmed by PWM signal through PWM pin, it
can run at frequencies higher than 200Hz.
