Frequently Asked Questions
What input voltage range does TPS92682QRHBRQ1 support for automotive battery systems?
TPS92682QRHBRQ1 supports an input voltage range of 4.5 V to 65 V, with a nominal operating voltage of 14 V. This wide range accommodates standard 12 V automotive battery rails including load-dump transients up to 65 V, making it suitable for robust vehicle LED driver designs.
How does TPS92682QRHBRQ1 manage two LED strings simultaneously in a headlight module?
The device provides dual independent constant-current control channels, each regulated via pulse-width modulation in current-mode control. The SPI interface allows the host microcontroller to configure current levels and dimming duty cycles for each of the 2 channels independently, enabling precise beam control for high-beam and low-beam strings within a single 32-pin QFN IC.
Is TPS92682QRHBRQ1 certified for automotive-grade applications and what qualification standard applies?
Yes, TPS92682QRHBRQ1 carries AEC-Q100 automotive qualification and is manufactured as a Q1-grade component per Texas Instruments' automotive product designation. The device is RoHS-compliant (JESD-609 e4 code) and rated for the -40°C to +125°C temperature range required in automotive under-hood and body control applications.
