CAT9552 Datasheet 16-channel I2c-bus Led Driver

Manufacturer: onsemi

Overview: .. CAT9552 16-Channel I2C-bus LED Driver with Programmable Blink.

General 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.

The CAT9552 is patible with I2C and SMBus applications where it is desireable to limit the bus traffic or free-up the bus master’s internal timer.

Key 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.
