The Texas Instruments TPS929121QPWPRQ1 is a 12-channel automotive-grade LED driver designed for high-side current sourcing applications. It supports a wide input voltage range from 4.5V to 40V, with each channel capable of delivering up to 75mA of current, set by an external resistor. The device features high current accuracy, with less than ±5% deviation at 5 mA to 75 mA.
This LED driver offers advanced dimming capabilities, including 12-bit independent PWM dimming with programmable frequencies up to 20 kHz, as well as linear and exponential dimming methods. It utilizes a FlexWire control interface supporting clock frequencies up to 1 MHz, allowing for up to 16 devices on a single bus. The TPS929121QPWPRQ1 includes comprehensive diagnostic and protection features such as LED open-circuit detection, thermal error flags, and programmable fail-safe states.
Packaged in a 24-HTSSOP, the TPS929121QPWPRQ1 is AEC-Q100 qualified for automotive applications, operating within a temperature range of -40°C to 125°C. It also provides a 5V LDO output suitable for supplying a CAN transceiver, making it a versatile solution for automotive lighting systems.
