Description:

The TPS92662A-Q1 LED matrix manager deviceenables fully dynamic adaptive lighting solutions byproviding individual pixel-level LED control. Thedevice includes four sub-strings of three seriesconnected integrated switches for bypassingindividual LEDs. The individual sub-strings allow thedevice to accept either single or multiple currentsources.The TPS92662A-Q1 features a programmable Piercecrystal oscillator driver. Optimal performance isachieved by selecting the driver strength based onthe quartz crystal or ceramic resonator manufacturersrecommendations. The device also incorporates aselectable drive strength clock buffer. The rise andfall times and the EMI generated by clock signal iscontrolled by varying the drive strength of the clockbuffer. When necessary, the clock buffer can bedisabled to eliminate the noise generated by the clocksignal and provide the lowest EMI performance.The TPS92662A-Q1 supports the multi-drop universalasynchronous receiver transmitter (UART) serialinterface and is compatible with TPS92662-Q1 andTPS92663-Q1 devices. The I2C communicationinterface can be used to read from and write to anexternal EEPROM that can store system calibrationdata.An on-board 8-bit ADC with two multiplexed inputscan be used for system temperature compensationand used to measure a binning value which allows forLED binning and coding.
