The ISO672xB devices are high-performance, dual-channel digital isolators ideal for cost sensitive applications requiring up to 3000 VRMS (D package) isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC.

The ISO672xB devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by TI’s double capacitive silicon dioxide (SiO2) insulation barrier. The ISO6720B device has 2 isolation channels with both channels in the same direction. The ISO6721B device has 2 isolation channels with 1 channel in each direction. In the event of input power or signal loss, the default output is high for devices without suffix F and low for devices with suffix F. See Device Functional Modes section for further details.

Used in conjunction with isolated power supplies, these devices help prevent noise currents on data buses, such as UART, SPI, RS-485, RS-232, and CAN from damaging sensitive circuitry. Through innovative chip design and layout techniques, the electromagnetic compatibility of the ISO672xB devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO672xB family of devices is available in a 8-pin SOIC narrow-body (D) package and is a pin-to-pin upgrade to the older generations. For reinforced isolation requirements, refer to the ISO672x-Q1.

參考設計

TIDA-010243 — 具備獨立 ADC 的三相比流器電表參考設計

此參考設計利用高效能、多通道類比轉數位轉換器 (ADC) 實作 0.1 級三相能源量測,其會在 8 kHz 時對比流器 (CT) 取樣,以量測 AC 主電源各腳的電流與電壓。此參考設計可在 0.05 A 至 100 A 的廣泛輸入電流範圍中實現高準確度,並支援如獨立諧波分析等電源品質功能所需的高取樣頻率。使用 TI Arm® Cortex®-M0+ 主機微控制器進行量測時,即可實現 32 kSPS 的 ADC 取樣率。透過將 TI ADC 能源量測程式庫移植至 MSPM0G3507,即可實作必要的軟體功能,且可與 Code Composer Studio™ 彙整。
