Front Panel LED Control/Driver Power with Standby Management (PT6991)

Front Panel LED Control/Driver Power with Standby Management

Product ID: PT6991

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. The PT6991 is housed in 32-pin SOP package. Pin assignments and application circuit are optimized for easy PCB layout and cost saving
advantages.
