1.
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 capacitance. As such, the
PCA9621 can be connected to other 2-wire devices across long cable connections.
It can be mixed with other Fast-mode Plus slaves in systems driven by Fm+ buffers or by
the PCA9646 (fully buffered 4-channel bus switch) to build large scale systems with
high-speed or high-capacitance drive capability, for example large scale LED displays or
controlled lighting.
