General Description

The PCA9922 is an 8-channel constant current LED driver designed for LED signage and display applications.

The output current is adjustable from 15 mA to 60 mA controlled by an external series resistor.

The outputs are controlled via a serial interface with a maximum clock frequency of 25 MHz to allow for the system requirement of high volume data transmission.

Key Features

  • 25 MHz serial interface.
  • 3.3 V to 5.5 V operation.
  • 8 LED low side constant current outputs.
  • Global control for the 8 LED outputs variable between 15 mA to 60 mA.
  • 15 mA to 60 mA maximum current for all 8 output channels set by an external resistor.
  • Constant current matching at 25 °C, VDD = 5.0 V.
  • Bit-to-bit: ±6 %.
  • Chip-to-chip: ±10 %.
  • Gradual turn-on/turn-off output to limit EMI.
  • Error detection mode for li.
