The TPS92662A-Q1 LED matrix manager device enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control. The device includes four sub-strings of three series-connected integrated switches for bypassing individual LEDs. The individual sub-strings allow the device to accept either single or multiple current sources.
The TPS92662A-Q1 features a programmable Pierce crystal oscillator driver. Optimal performance is achieved by selecting the driver strength based on the quartz crystal or ceramic resonator manufacturers recommendations. The device also incorporates a selectable drive strength clock buffer. The rise and fall times and the EMI generated by clock signal is controlled by varying the drive strength of the clock buffer. When necessary, the clock buffer can be disabled to eliminate the noise generated by the clock signal and provide the lowest EMI performance.
The TPS92662A-Q1 supports the multi-drop universal asynchronous receiver transmitter (UART) serial interface and is compatible with TPS92662-Q1 and TPS92663-Q1 devices. The I2C communication interface can be used to read from and write to an external EEPROM that can store system calibration data.
An on-board 8-bit ADC with two multiplexed inputs can be used for system temperature compensation and used to measure a binning value which allows for LED binning and coding.
The internal charge pump rail supplies the gate drive voltage for the LED bypass switches. The low on-resistance (RDS(on)) of the bypass switch minimizes conduction loss and power dissipation.
The TPS92662A-Q1 and TPS92662-Q1 both incorporate identical register settings for programming phase shift and pulse width of each individual LED in the string and for reporting LED open and short circuit faults.
