The AMC23C12 is an isolated window comparator with a short response time. The open-drain output is separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5kVRMS according to VDE 0884-17 and UL1577, and supports a working voltage of up to 1kVRMS.

The comparison window is centered around 0V, meaning that the comparator trips if the absolute value of the input voltage exceeds the trip threshold value. The trip threshold is adjustable from 20mV to 300mV through a single external resistor and, therefore, the comparison window ranges from ±20mV to ±300mV. When the voltage on the REF pin is greater than 550mV, the negative comparator is disabled and only the positive comparator is functional. The reference voltage in this mode ranges as high as 2.7V. This mode is particularly useful for monitoring voltage supplies.

The open-drain output on the device supports transparent mode (LATCH input tied to GND2) where the output follows the input state, or latch mode, where the output is cleared on the falling edge of the latch input signal.

The AMC23C12 is available in an 8-pin, wide-body SOIC package and is specified over the full automotive temperature range of –40°C to +125°C.

TIDA-011012 — 適合中壓應用的 50kW SiC 式模組化固態變壓器參考設計

此設計實作以碳化矽 (SiC) 電源模組為基礎的三相固態變壓器 (SST)。使用模組化架構可實現串聯多個轉換器子模組，以滿足中壓電網需求。使用快速切換 SiC 裝置可讓 DC/AC 級在 10kHz 時切換，並可在 100kHz 時切換雙主動橋式 (DAB) 隔離級，進而縮減高頻磁性元件的尺寸，並增加整體功率密度。模組間通訊可提供中壓終端設備所需的高隔離電壓位準。串接拓撲結構均勻地將電網電壓分配給子模組，允許使用標準的低電壓額定 SiC 裝置，同時維持完整中壓運作。
