Description of tps92662-q1

Tps92662-q1 LED matrix manager device realizes a fully dynamic adaptive lighting solution by providing a single pixel level led control.

The 3 Series Integrated switches of the device each have 4 sub lamp strings, which can bypass a single LED. Each sub lamp string allows the device to accept single or multiple current sources. It also allows up to four switches to be connected in parallel for winding over current LEDs.

The tps92662-q1 device is controlled and managed by the main microcontroller through the multipoint universal asynchronous receiver transmitter (UART) serial interface. The serial interface supports the use of can transceiver, which is suitable for more reliable and robust physical layer. The I2C communication interface is used to read data from or write data to an external EEPROM that stores system calibration data.

An on-board 8-bit ADC with two multiplexed inputs can be used for system temperature compensation and for measuring the grading value to achieve led grading and coding.

The internal charge pump rail provides the grid drive voltage for the LED bypass switch. The low resistance (RDS (on)) of the bypass switch minimizes conduction loss and power dissipation.

The phase shift and pulse width of each LED in the lamp string are programmable. The device uses an internal register to adjust the PWM frequency. Multiple devices can be synchronized. During PWM dimming operation, the switch conversion has a programmable voltage swing rate, which is used to alleviate EMI problems.

The device has open circuit led protection function (with programmable threshold). The serial interface will report an open LED or a short led fault.
