[SO24 7,5mm]
€2.40

PCA9532D 16bit I2C LED dimmer

The PCA9532 is a 16-bit I2C-bus and SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.

Features:

  • 16 LED drivers (on, off, flashing at a programmable rate)
  • 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.591 and 152 Hz (1.69 seconds and 6.58 milliseconds)
  • 256 brightness steps
  • 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 reset input
  • 16 open drain outputs directly drive LEDs to 25 mA
  • Controlled edge rates to minimize ground bounce
  • No glitch on power-up
  • Supports hot insertion
  • Low stand-by current
  • Operating power supply voltage range of 2.3 V to 5.5 V
  • 0 kHz to 400 kHz clock frequency
  • DATASHEET.
