24 LED drivers. Each output programmable at:
1 MHz Fast-mode Plus compatible I
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 97 kHz PWM signal
256-step group brightness control allows general dimming (using a 190 Hz PWM
signal) from fully off to maximum brightness (default)
256-step group blinking with frequency programmable from 24 Hz to 10.73 s and
duty cycle from 0 % to 99.6 %
24 open-drain outputs can sink between 0 mA to 100 mA and are tolerant to a
maximum off state voltage of 40 V. No input function.
Output state change programmable on the Acknowledge or the STOP Command to
update outputs byte-by-byte or all at the same time (default to ‘Change on STOP’).
Active LOW Output Enable (OE) input pin allows for hardware blinking and dimming of
the LEDs
7 hardware address pins allow 126 PCA9626 devices to be connected to the same
I
4 software programmable I
LED Sub Call addresses) allow groups of devices to be addressed at the same time in
any combination (for example, one register used for ‘All Call’ so that all the PCA9626s
on the I
three different addresses so that
same time in a group). Software enable and disable for I
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
I
25 MHz internal oscillator requires no external components
Internal power-on reset
Noise filter on SDA/SCL inputs
No glitch on power-up
Supports hot insertion
Low standby current

5.5 V tolerant inputs on non-LED pins
ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per
JESD22-A115 and 1000 V CDM per JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
