The PCA9622DR is a 16-bit Fm+ I2C-bus 100mA 40V 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 10.73seconds 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.
Active low output enable (OE) input pin allows for hardware blinking and dimming of the LEDs
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
No glitch on power-up
Supports hot insertion
Low standby current
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
