PCA9634  
8-bit Fm+ I2C-bus LED driver  
Rev. 7.1 — 18 December 2017  
Product data sheet  
1. General description  
The PCA9634 is an I2C-bus controlled 8-bit LED driver optimized for  
Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED output has its own  
8-bit resolution (256 steps) fixed 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 specific brightness value. An additional 8-bit resolution (256 steps) Group PWM  
controller has both a fixed 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 LED output driver is  
programmed to be either open-drain with a 25 mA current sink capability at 5 V or  
totem-pole with a 25 mA sink, 10 mA source capability at 5 V. The PCA9634 operates with  
a supply voltage range of 2.3 V to 5.5 V and the outputs are 5.5 V tolerant. LEDs can be  
directly connected to the LED output (up to 25 mA, 5.5 V) or controlled with external  
drivers and a minimum amount of discrete components for larger current or higher voltage  
LEDs.  
The PCA9634 is one of the first 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) allows asynchronous control of the LED  
outputs and can be used to set all the outputs to a defined I2C-bus programmable logic  
state. The OE can also be used to externally PWM the outputs, which is useful when  
multiple devices need to be dimmed or blinked together using software control.  
Software programmable LED Group and three Sub Call I2C-bus addresses allow all or  
defined groups of PCA9634 devices to respond to a common I2C-bus address, allowing  
for example, all red LEDs to be turned on or off at the same time or marquee chasing  
effect, thus minimizing I2C-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 PCA9634  
through the I2C-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 reconfigure all device registers to the same condition.
