美国史普拉格(SPRAGUE)公司的两种汽车用集成电路可分别完成对车辆灯光的故障报警和各种液体液位的检测报警功能。这两组器件都是单片双极型集成电路,其共同特点是适应温度范围宽,性能稳定,抗干扰能力强,具有内部稳压、反压保护和温度补偿功能,灵敏度高,成本低。对于灯光监视电路来说,即使器件损坏, 也不会影响到线路的正常工作。 SPRAGUE company’s two automotive integrated circuits can be completed on the vehicle lighting fault alarm and a variety of liquid level detection alarm. Both devices are monolithic bipolar integrated circuits. Their common features are wide temperature range, stable performance, strong anti-interference ability, internal voltage regulation, back-pressure protection and temperature compensation, high sensitivity and low cost. For the light monitoring circuit, even if the device is damaged, it will not affect the normal operation of the line.
