TPS929120AQPWPRQ1

The TPS929120AQPWPRQ1 from Texas Instruments is a 12-channel, 40V high-side LED driver specifically designed for automotive lighting applications. It offers precise control over LED current and PWM duty cycles, enabling advanced animation effects in exterior and interior lighting.

The device supports a supply voltage range of 4.5 V to 40 V and provides up to 75 mA of channel current, with high accuracy maintained across various current levels. It features 12-bit independent PWM dimming and a programmable PWM frequency up to 20 kHz, allowing for flexible lighting control. The FlexWire control interface supports up to 1-MHz clock frequency and enables communication with up to 16 devices on a single bus, facilitating long-distance off-board communication without impacting EMC.

Integrated diagnostic and protection features include LED open-circuit detection, LED short-circuit detection, and programmable fail-safe states. The TPS929120AQPWPRQ1 is AEC-Q100 qualified for automotive applications, operating within a temperature range of -40°C to +125°C. It is available in a 24-HTSSOP package suitable for surface mounting.

This LED driver is ideal for applications such as automotive exterior rear and headlights, interior ambient lighting, and cluster displays where independent LED control and robust communication are essential.
