Texas Instruments  TPS92662QPHPRQ1

The TPS92662-Q1 LED matrix manager device enables fully dynamic adaptive lightingsolutions by providing individual pixel-level LED control.

The device includes four sub-strings of three series-connected integrated switches forbypassing individual LEDs. The individual sub-strings allows the device to accept either single ormultiple current sources, as well as paralleling up to four switches for bypassing high currentLEDs.

The device contains a multi-drop universal asynchronous receiver transmitter (UART)serial interface for control and management by a master microcontroller. The serial interfacesupports the use of CAN transceivers for a more robust physical layer. TheI2C communication interface can be used to read from and write to anexternal EEPROM that can store system calibration data.

An on-board 8-bit ADC with two multiplexed inputs can be used for system temperaturecompensation such as binning and coding.

The internal charge pump rail that can float up to 69 V above GND provides the LED bypassswitch gate drive supply. The low on-resistance (RDS(on)) of the bypassswitch minimizes conduction loss and power dissipation.

The phase-shift and pulse-width are programmable for each individual LED in the string.The PWM frequency is adjustable via an internal register and multiple devices can be synchronized.In addition, the switch transitions during PWM dimming operation have a programmable slew ratelimit to mitigate EMI concerns.

The device features open LED protection with programmable threshold as well as open andshort LED fault reporting via the serial interface.
