PT6991 Overview
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. In standby operation, the PT6991 provides the standby power management to the chipset for low power consumption.
