Overview
PCA9635 16-bit Fm+ I2C-bus LED driver Rev.
07 — 16 July 2009 Product data sheet 1.
General description The PCA9635 is an I2C-bus controlled 16-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 PCA9635 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 PCA9635 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 PC...
