具有多斜率热折返控制和内置 ADC 的汽车级双通道 10 位智能 DAC

The 10-bit AFE53902-Q1 and 8-bit AFE43902-Q1 devices ( AFEx3902-Q1) are dual-channel, smart analog front ends (AFE) targeted for multislope thermal foldback of LED lighting. The output of LED lights reduce with an increase in temperature. Multislope thermal foldback helps maintain a steady light out • AEC-Q100 qualified for automotive applications: \n• Multislope thermal foldback \n• Digital-to-analog converter (DAC) output \n• 8-bit ( AFE43902-Q1)\n• Pulse Width Modulation (PWM) output with 7‑bit duty cycle\n• Look-up table (LUT) based parameter configuration\n• Automatically detects I 2C or S;
