PCA9625
16-bit Fm+ I 2 C-bus 100 mA 24 V LED driver
Rev. 02 — 15 January 2008
Product data sheet
1. General description
The PCA9625 is an I 2 C-bus controlled 16-bit LED driver optimized for voltage switch
dimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs. Each LED output
has its own 8-bit resolution (256 steps) ?xed frequency individual PWM controller that
operates at 97 kHz with a duty cycle that is adjustable from 0 % to 99.6 % to allow the
LED to be set to a speci?c brightness value. An additional 8-bit resolution (256 steps)
group PWM controller has both a ?xed frequency of 190 Hz and an adjustable frequency
between 24 Hz to once every 10.73 seconds with a duty cycle that is adjustable from 0 %
to 99.6 % that is used to either dim or blink all LEDs with the same value.
Each LED output can be off, on (no PWM control), set at its individual PWM controller
value or at both individual and group PWM controller values. The PCA9625 operates with
a supply voltage range of 2.3 V to 5.5 V and the 100 mA open-drain outputs allow
voltages up to 24 V.
The PCA9625 is one of the ?rst LED controller devices in a new Fast-mode Plus (Fm+)
family. Fm+ devices offer higher frequency (up to 1 MHz) and more densely populated bus
operation (up to 4000 pF).
The active LOW Output Enable input pin (OE) blinks all the LED outputs and can be used
to externally PWM the outputs, which is useful when multiple devices need to be dimmed
or blinked together without using software control.
Software programmable LED Group and three Sub Call I 2 C-bus addresses allow all or
de?ned groups of PCA9625 devices to respond to a common I 2 C-bus address, allowing
for example, all red LEDs to be turned on or off at the same time or marquee chasing
effect, thus minimizing I 2 C-bus commands. Seven hardware address pins allow up to
126 devices on the same bus.
The Software Reset (SWRST) Call allows the master to perform a reset of the PCA9625
through the I 2 C-bus, identical to the Power-On Reset (POR) that initializes the registers to
their default state causing the outputs to be set HIGH (LED off). This allows an easy and
quick way to recon?gure all device registers to the same condition.
The PCA9625 and PCA9635 software is identical and if the PCA9625 on-chip 100 mA
NAND FETs do not provide enough current or voltage to drive the LEDs, then the
PCA9635 with larger current or higher voltage external drivers can be used.
