- SPI interface allows real-time digital configuration of operating parameters, enabling dynamic adjustment of current levels and fault thresholds from a microcontroller
- Wide 4.5V to 65V input voltage range covers 12V, 24V, and 48V automotive bus standards for flexible deployment in body lighting and ADAS power stages
- AEC-Q100 qualified with -40C to 125C operating range ensures reliable operation across the full automotive temperature spectrum including under-hood environments
Applications
The TPS92682QRHMQ1 is designed for automotive LED lighting systems, including headlamps, tail lamps, and interior ambient lighting, where independent dual-channel current control and dimming via SPI are required. Its wide input voltage range and current-mode PWM control make it also suitable for automotive DC/DC converter stages powering ADAS sensors, cameras, and infotainment systems. The AEC-Q100 qualification and 125C maximum junction temperature make it a robust choice for high-reliability automotive electronic control units (ECUs).

Frequently Asked Questions
What control modes does the TPS92682QRHMQ1 support?
The TPS92682QRHMQ1 uses current-mode pulse width modulation (PWM) control for both of its dual output channels. Current-mode control improves transient response and simplifies loop compensation compared to voltage-mode control, making it well-suited for LED current regulation and point-of-load power conversion in automotive systems.
What is the input voltage range of the TPS92682QRHMQ1?
The TPS92682QRHMQ1 accepts input voltages from 4.5V minimum to 65V maximum, with a nominal operating point of 14V for standard automotive 12V battery systems. The wide range also accommodates 24V truck systems and 48V mild hybrid architectures, making the part versatile across different automotive platform voltages.
How does the SPI interface benefit automotive lighting designs?
The SPI interface on the TPS92682QRHMQ1 allows a host microcontroller to dynamically configure output current levels, dimming ratios, and fault thresholds at runtime. This enables adaptive headlight intensity control, animated turn signals, and in-system diagnostics without hardware changes, supporting more flexible and intelligent automotive lighting architectures.
What package does the TPS92682QRHMQ1 come in?
The TPS92682QRHMQ1 is available in a 32-Pin VQFN (Very thin Quad Flat No-Lead) package (JESD-30 Code: S-PQCC-N32). The exposed thermal pad on the bottom of the package facilitates efficient heat transfer to the PCB, which is important for high-current LED driver applications in thermally constrained automotive environments.
Is the TPS92682QRHMQ1 suitable for 48V mild hybrid vehicle platforms?
Yes, the TPS92682QRHMQ1's maximum input voltage of 65V provides adequate margin for 48V nominal systems that can spike to 58V or higher during load dump events in mild hybrid vehicles. Combined with its AEC-Q100 qualification and -40C to 125C temperature range, it is well-positioned for next-generation automotive 48V LED and power management applications.
