PT6991 - Front Panel LED Control/Driver Power

General Description

The PT6991 is designed to integrate the LED driver, key-scan matrix, infrared (IR) remote control decoding and into one integrated solution.

All functions are programmable using I2C interface.

Key Features

  • IC front panel LED controller driver.
  • Standby power management to the host.
  • 5.0V (VDD) supply and 3.3V interface for the IC.
  • IR remote control decoder (Philips, NEC, Thomson, Sony, Matsushita).
  • Multiple display modes ( 10 segments and 6 digits to 12 segments and 4 digits ).
  • External resistors necessary for all logic outputs (N-CH. Open drain).
  • Key scanning (up to 10 x 1 matrix = 10 keys).
  • I2C serial interface (SCL, SDA) com.
