The TRS3232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV IEC ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.

参考设计

TIDA-01094 — 适用于隔离式分流电流测量的抗磁场干扰、无变压器电源参考设计

TIDA-01094 参考设计通过使用隔离式 Δ-Σ 调制器实现了具有隔离式分流传感器的 0.5 类三相无变压器能量测量系统。Δ-Σ 调制器使其输出电路与输入电路进行电容性隔离,从而提供无变压器的数据隔离。每个调制器的高侧由一个同样无变压器的电容压降电源供电。由于在这种设计中不使用变压器,因此这种设计与生俱来就能抗磁性干扰。此外,高侧电容压降电源降低了整体系统成本,具有固有的低传导和辐射发射,并且由于高侧单独由市电供电而非来自低侧电源,因此减少了从低侧电源消耗的电流。
