CAT9552 - 16-Channel I2C-bus LED Driver

Description

The CAT9552 is a 16-channel, parallel input/output port expander optimized for LED On/Off and blinking control.

Each individual LED may be turned ON, OFF, or set to blinking at one of two programmable rates.

Features

  • 16 LED drivers with On/Off and programmable blink rate control.
  • 2 selectable, programmable blink rates:.
  • frequency: 0.172Hz to 44Hz.
  • duty cycle: 0% to 99.6%.
  • 16 open drain outputs drive 25mA each.
  • I/Os can be used as GPIOs.
  • 400kHz I2C bus compatible.
  • 2.3V to 5.5V operation.
  • 5V tolerant I/Os.
  • Active low reset input.
  • RoHS-compliant 24-Lead SOIC, TSSOP and 24-pad TQFN (4 x 4mm) packages.
