产品详细说明

TPS92664QPHPRQ1 is Texas Instruments' 16-channel automotive LED matrix manager in a 48-pin HTQFP package, using integrated bypass switches to address individual LEDs in a headlamp matrix.

Four groups of four switches let one module build independently controlled light segments, while ten-bit PWM settings shape each segment's intensity without changing the source current for the entire string.

An internal oscillator and LVDS clock path help synchronize multiple matrix devices, so a larger adaptive lamp can coordinate transitions instead of producing visible timing differences between segments.

The onboard ADC monitors LED voltage, current and die temperature for fault and thermal decisions, and EEPROM retains defaults and calibration values when the host is unavailable at power-up.

Its UART control and AEC-Q100 Grade 1 qualification make the device a specific fit for automotive adaptive lighting rather than a standalone constant-current LED supply.
