Voltage-switch drivers, constant-current
drivers, and Flash LED drivers
LED controllers
LEDs are used in a wide range of applications, from low-end status indicators to high-end video displays. System designers often
need the ability to control these LEDs, but can’t afford to tie up the system processor to do so. NXP’s LED controllers solve this
problem, performing a variety of control tasks while ofoading the system processor. Having sent instructions to the LED controller,
the processor is free to engage in other tasks or go into a low-power state.
NXP’s LED controllers offer a variety of features needed in LED-driving applications. Some of these features include:
} Blinking and dimming capability
} Pulse-width modulation (PWM) for LED control
} Color mixing capabilities
} Fast-mode Plus (Fm+) communication channel with data transfer rate of up to 1 Mbps over the I
2
C-bus.
} Different output drive types (push-pull, open-drain voltage switch or constant-current driver)
} Independent control of LEDs
} LED status and fault reading
} Short-circuit protection
} Over-temperature protection
Voltage-Switch Drivers
Voltage-switch output driver devices control the LED
connected to the output pin by switching the connection
to ground or supply on or off. A series resistor connected
between the LED and the device limits the current that ows
through the LED into the device.
Voltage-switch devices have the advantage of dissipating the
heat outside the device, in the series resistor. Therefore the
device is insensitive to heat dissipation and is good for driving
multiple LEDs in series, with different forward-bias voltages
(V
f
), from the same supply.
Constant-Current Drivers
A current-regulated LED driver results in the LED light
remaining constant with the supply-voltage uctuations.
NXP constant-current LED drivers are used for low-current
luminary lighting applications requiring accurate lighting
control independent of supply voltage, temperature, and LED
forward-bias voltage.
Flash LED Drivers
NXP Flash LED Drivers are high-efciency, maximum-output,
small footprint devices with touch capability and an indicator
LED output feature. These devices are highly integrated with
hardware and I
2
C interface modes.
The devices are classied in three groups: voltage-switch drivers, constant-current drivers, and Flash LED drivers.
These groups are discussed below.
The LED controllers are supported by application boards and daughter cards, an established manufacturing infrastructure that
supports high volumes, and several technical documents. NXP helps system designers make lighting affordable, in everything
from indoor consumer electronics and appliances to outdoor decorative lighting.
