Product Highlight

  • Supply Voltage: 2.3 to 5.5 V
  • Output Current per Channel: 25 mA
  • Output Voltage: 5.5 V
  • Switching Frequency-Max: 400 kHz

The PCA9632DP2,118 is an I2C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. The PCA9632 is a drop-in upgrade for the PCA9633 with 40x power reduction.

In Individual brightness control mode, each LED output has its own 8-bit resolution (256 steps) fixed frequency Individual PWM controller that operates at 1.5625 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.

The PCA9632 is in the 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).


  • 40x power reduction compared to PCA9633
  • 4 LED drivers. Each output programmable at:
    • Off
    • On
    • Programmable LED brightness
    • Programmable group dimming/blinking mixed with individual LED brightness
  • 1 MHz Fast-mode Plus I2C-bus interface with 30 mA high drive capability on SDA output for driving high capacitive buses
  • 256-step (8-bit) linear programmable brightness per LED output varying from fully off
    (default) to maximum brightness using a 1.5625 kHz PWM signal in Individual brightness mode
  • 64-step (6-bit) linear programmable brightness for each LED output varying from fully off (default) to maximum brightness using a 6.25 kHz PWM signal in group dimming mode
  • Internal power-on reset
  • Noise filter on SDA/SCL inputs
  • Edge rate control on outputs
  • No glitch on power-up
  • Supports hot insertion
  • Low standby current of < 1 µA
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 5.5 V tolerant inputs
  • -40°C to +85°C operation
  • ESD protection exceeds 5000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
  • Packages offered: TSSOP8, TSSOP10, HVSON8, HVSON10


  • RGB or RGBA LED drivers for color mixing
  • LED status information
