PCA9635PW,118

PCA9635PW,118 is a 16-bit Fm+ I²C-bus LED driver optimized for red/green/blue/amber (RGBA) colour mixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97kHz 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 190Hz and an adjustable frequency between 24Hz to once every 10.73seconds 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. 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 1MHz) and more densely populated bus operation (up to 4000pF). Applications include RGB or RGBA LED drivers, LED status information, LED displays, LCD backlights, keypad backlights for cellular phones or handheld devices.

• Software reset feature (SWRST call) allows the device to be reset through the I²C-bus
• Internal power-on reset, noise filter on SDA/SCL inputs
• Operating power supply voltage range of 2.3V to 5.5V
• 5.5V tolerant inputs
• No glitch on power-up, supports hot insertion
• Low standby current
• Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
• TSSOP28 package
• Operating temperature range from -40°C to 85°C
• 7 hardware address pins allow 126 devices to be connected to the same I2C-bus
