General description
The PCA9621 is a monolithic
CMOS integrated circuit for general purpose output drive configurable from a 2-wire bus interface (including I2C-bus, SMBus, PMBus, and other systems based on similar principles).
Output ports have a 65 mA sink capability, making them ideal for driving LEDs.
The state of the outputs is determined by a programmable 8-bit register which can be read and written via signals from the 2-wire bus (e.
g.
, I2C-bus or similar).
The 2-wire bus interface also has 30 mA Fast-mode Plus (Fm+) capability, and consequently can be run in excess of 1 MHz or up to 4000 pF capaci...
