PCA9621  
65 mA 8-bit 2-wire bus output port  
Rev. 1 — 9 March 2011  
Product data sheet  
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.  
2. Features and benefits  
„ 8 individually selectable open-drain output ports  
„ 65 mA static sink capability on all output ports  
„ Ports may be paralleled for up to 500 mA drive  
„ Ideal for simple LED or general purpose output drive  
„ Fast-mode Plus (30 mA, 4000 pF) 2-wire bus capability  
„ Works with I2C-bus (Standard-mode, Fast-mode, and Fast-mode Plus), SMBus  
(standard and high power mode), and PMBus  
„ Fast switching times allow operation in excess of 1 MHz  
„ Operating voltages from 2.7 V to 5.5 V  
3. Applications  
„ LED and 7-segment displays  
„ Simple high-power (500 mA) LED dimming  
„ General purpose output  
„ Instrumentation indicators
