The DAC43901-Q1 and DAC43902-Q1 ( DAC4390x-Q1) are a family of automotive, 8-bit smart DACs with dual and quad PWM outputs. The DAC43901-Q1 provides two PWM outputs, and the DAC43902-Q1 provides four PWM outputs. The DAC channels also act as trigger inputs or outputs. The DAC4390x-Q1 provides a preconfigured state machine that logic generates logarithmic dimming with configurable timings. The PWM-based logarithmic dimming is applicable in logarithmic fade-in and fade-out applications in automotive interior and exterior lighting. The DAC4390x-Q1 also support sequential animation applicable for automotive turn-indicator lights. These devices provide NVM for storing the configurations. These smart DACs function without the need for a processor ( processor-less operation) using GPIOs and NVM. These devices automatically detect I 2C or SPI and have an internal reference. The feature set combined with the tiny package and low power make the smart DACs an excellent choice for applications in automotive light animation.
