概览

NCS5651 是一款高能效,A/B 级,低失真电力线通信驱动器。它适用于从电力线载波 (PLC) 调制解调器接受信号。该器件由两个运算放大器 (opamps) 组成。输出运算放大器适用于将最高 2 A 峰值电流驱动至隔离变压器或耦合电源的简单线圈中。在 1.5 A 输出电流下,输出电压可保证两个轨 1 V 以下的摆幅,为用户提高了 SNR。 除了输出放大器之外,还提供了小信号运算放大器,可以配置为一致增益跟踪缓冲器,或者提供 4 极低通过滤器的第一级。NCS5651 提供了电流限值,可使用单电阻、R 限值和电流限值标志仪器对其进行编程。该器件提供两个带迟滞的独立热标志:让用户了解内部结温度达到用户编程的热警告阈值的热警告标志,表明内部结温度超过 150 °C 的热错误标志。NCS5651 的电源电压范围为 6-12 V。可以关断,使得输出处于高阻抗状态。NCS5651 采用带裸露热焊盘的 20 引线 QFN 封装 (4x4x1 mm3),提高了热可靠性。
