Applications
The TPS92662-Q1 is designed for automotive adaptive driving beam (ADB) and pixel-light headlight systems where individual LED segments must be independently dimmed to avoid glare for oncoming traffic. It supports 12 V to 65 V vehicle bus voltages, making it compatible with both conventional 12 V and 48 V mild-hybrid electrical systems. ADAS lighting designers use this device in high-resolution matrix modules containing 25 or more LED segments per headlight unit.

Frequently Asked Questions
How many LED channels can TPS92662-Q1 manage and what dimming resolution does each channel offer?
The TPS92662-Q1 manages 12 independent LED channels, each with 10-bit PWM dimming resolution providing 1024 discrete brightness steps. This fine granularity allows adaptive headlights to create smooth beam patterns with less than 0.1% brightness step artifacts, meeting automotive glare-control standards.
Which supply voltage range does TPS92662-Q1 support and does it operate in 48 V mild-hybrid vehicle architectures?
TPS92662-Q1 operates with input voltages from 12 V to 65 V, covering both standard 12 V automotive systems and 48 V mild-hybrid architectures. The 65 V maximum rating also accommodates load-dump transients up to 60 V, reducing the need for additional transient suppression components in headlight power stages.
How does daisy-chaining multiple TPS92662-Q1 devices scale up a pixel-headlight system beyond 12 channels?
Multiple TPS92662-Q1 ICs connect in SPI daisy-chain topology, allowing systems to address 24, 36, or more LED channels from a single MCU SPI port. Each device uses an integrated CRC check on 16-bit SPI frames to detect transmission errors, ensuring pixel accuracy in safety-critical ADB beam-shaping applications operating at -40°C to +125°C.
