Product Overview

The PCA9626B,118 is an I²C-bus controlled 24-bit LED Driver optimized for voltage switch dimming and blinking 100mA red/green/blue/amber (RGBA) LEDs. 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 10.73 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 PCA9626 operates with a supply voltage range of 2.3 to 5.5V and the 100mA open-drain outputs allow voltages up to 40V.
  • Active low output enable (OE) input pin allows for hardware blinking and dimming of the LEDs
  • A chase byte allows execution of predefined ON/OFF pattern for the 24 LED outputs
  • Software reset feature (SWRST call) allows the device to be reset through the I²C-bus
  • Internal power-ON reset
  • Noise filter on SDA/SCL input
  • No glitch on power-up
  • Supports hot insertion
  • Low standby current consumption
  • ESD protection exceeds 2000V HBM per JESD22-A114 and 1000V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
  • 25MHz Internal oscillator requires no external components
  • 5.5V Tolerant inputs on non-LED pins
