The TPS7H2201 is a single channel eFuse that provides configurable rise time to minimize inrush current and reverse current protection. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.5V to 7V and can support a maximum continuous current of 6A. The switch is controlled by an on and off input (EN), which is capable of interfacing directly with low-voltage control signals.

The TPS7H2201 is available in a ceramic and plastic package with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –55°C to 125°C.

TIDA-010191 — 航太級多通道 JESD204B 15-GHz 時脈參考設計

相位陣列天線和數位波束成形技術,是提高未來航太雷達成像和寬頻衛星通訊系統的性能的關鍵技術。數位波束成形與類比波束成形不同,通常每個天線元件需要一套資料轉換器。這些轉換器需要具有具體定義相位關係的時鐘。此參考設計展示如何透過已定義及可調整相位關係,產生低雜訊 MHz 至 GHz 時脈訊號。在發生單一事件後,甚至可能恢復時脈階段。透過操作兩個 ADC12DJ3200QML-SP 評估模組,及在 3.2 GHz 時其對應之 FPGA 架構擷取平台,以及 10-ps 板對板偏斜的情況,藉此來展示 JESD204B 支援。
