Product details

Description

The PCA9552 LED blinker blinks LEDs in I2C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I2C-bus controller's (MCU, MPU, DSP, chip set, etc.) timer.

Features

16 LED drivers (on, off, flashing at a programmable rate).
2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.172 Hz and 44 Hz (5.82 seconds and 0.023 seconds).
Input/outputs not used as LED drivers can be used as regular GPIOs.
Internal oscillator requires no external components.
I2C-bus interface logic compatible with SMBus.
Internal power-on reset.
Noise filter on SCL/SDA inputs.
Active LOW.
