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. 1 • • • • • • • • • 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 Multi-drop UART communication interface – Compatible with TPS92662-Q1 and TPS92663-Q1 devices – Compatible with CAN physical layer Eight-bit ADC with two MUXed inputs Programmable crystal oscillator driver and clock buffer strength – Improved radiated and conducted EMI performance External EEPROM I2C interface Programmable 10-bit PWM dimming LED open and short detection and protection Supports multi-LMM synchronization for more than 12-LED string via time division multiplexing 2 Applications • • • Automotive headlight systems ADB or glare-free high beam Sequential turn/animated daytime running lights 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 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. 2 Submit Documentation Feedback Copyright © 2019–2020, Texas Instruments Incorporated Product Folder Links: TPS92662A-Q1 TPS92662A-Q1 www.ti.com SLUSDV6A – OCTOBER 2019 – REVISED JANUARY 2020 6 Device and Documentation Support 6.1 Receiving Notification of Documentation Updates To receive notification of documentation updates, navigate to the device product folder on ti.com.

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. 6.5 Glossary SLYZ022 — TI Glossary.
