PCA9634

8-bit Fm+ I²C-bus LED driver

Rev. 04 — 5 January 2007

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.
