TPS92662-Q1 TPS92662-Q1 SLUSD15B – OCTOBER 2018 – REVISED JUNE 2020 SLUSD15B – OCTOBER 2018 – REVISED JUNE 2020 www.ti.com TPS92662-Q1 High-brightness LED Matrix Manager for Automotive Headlight Systems The device includes four sub-strings of three seriesconnected integrated switches for bypassing individual LEDs. The individual sub-strings allow the device to accept either single or multiple current sources. It also allows paralleling up to four switches for bypassing high current LEDs. 1 Features • • • • • • • • • • AEC-Q100 qualified for automotive applications – Grade 1: –40°C to 125°C ambient operating temperature – Device HBM classification level H1C – Device CDM classification level C5 Input voltage range: 4.5 V to 60 V 12 Integrated bypass switches – Four sub-strings of three series switches – 20-V maximum across switch – 62-V maximum switch to ground Multi-drop UART communication interface – Up to 31 addressable devices Compatible with CAN physical layer – Minimum number of wires in cable harness Eight-bit ADC with two MUXed inputs Crystal oscillator driver External EEPROM I2C interface Programmable 10-bit PWM dimming – Individual phase shift and pulse width – Device-to-device synchronization LED open and short detection and protection A master microcontroller is used to control and manage the TPS92662-Q1 devices via a multi-drop universal asynchronous receiver transmitter (UART) serial interface. The serial interface supports the use of CAN transceivers for a more robust physical layer. 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 onresistance (RDS(on)) of the bypass switch minimizes conduction loss and power dissipation. The phase shift and pulse width for each individual LED in the string are programmable. The device uses an internal register to adjust the PWM frequency. Multiple devices can be synchronized. The switch transitions during PWM dimming operation have a programmable slew rate to mitigate EMI concerns. 2 Applications • • • • Automotive headlight systems High-brightness LED matrix systems ADB or glare-free high beam Sequential turn and animated daytime running lights The device features open LED protection with programmable threshold. The serial interface reports open LED or short LED faults. 3 Description The TPS92662-Q1 LED matrix manager device enables fully dynamic adaptive lighting solutions by providing individual pixel-level LED control.

All other trademarks are the property of their respective owners. 5.4 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 5.5 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions.
