Package
The TPS61097A-33 provides a power supply solution for products powered by either a single-cell, two-cell, or three-cell alkaline, NiCd, or NiMH, or one-cell Li-Ion or Li-polymer battery. They can also be used in fuel cell or solar cell powered devices where the capability of handling low input voltages is essential. Possible output currents depend on the input-to-output voltage ratio. The devices provide output currents up to 100 mA at a 3.3-V output while using a single-cell Li-Ion or Li-Polymer battery. The boost converter is based on a current-mode controller using synchronous rectification to obtain maximum efficiency. The maximum average input current is limited to a value of 400 mA. The converter can be disabled to minimize battery drain. During shutdown, the battery is connected to the load to enable battery backup of critical functions on the load. The device is packaged in a 5-pin SOT-23 package (DBV) measuring 2.8 mm × 2.9 mm.

TPS61097AEVM-073 — TPS61097AEVM-073 評估模組
The TPS61097AEVM-073 evaluation module (EVM) demonstrates the Texas Instruments TPS61097A-33 synchronous boost converter. The input voltage range of the TPS61097A-33 is 0.9 to 5.5 V, which allows the device to operate from one-cell to three-cell battery configurations in addition to a single-cell (...)
TIDA-00480 — 汽車霍爾感測器旋轉編碼器
這是一款增量式旋轉編碼器，使用非接觸式磁性感測來偵測旋轉速度和方向。 兩組霍爾效應感測器測量 66 極環形磁鐵，並輸出兩組正交信號。 這套符合汽車標準的解決方案是傳統機械接觸式編碼器的替代方案，成本更低、可靠性更強，因為其採用的固態感測，不受實體磨損，灰塵、腐蝕和 RF 雜訊影響。
TIDC-CC3200SMARTPLUG — SimpleLink™ Wi-Fi® CC3200 智慧型插頭
越來越多的應用需要對 Wi-Fi 的能源測量和控制的支援，尤其是在智慧型插頭和智慧型插座等終端產品中，以及在家用電器、智慧型電網和樓宇自動化等一般應用領域中。
CC3200 智慧型插頭是一個完整的系統解決方案，它將計量資料運算整合到一個微控制器 (MCU) 中，並處理所有 Wi-Fi 通訊，包括連接到雲端伺服器的通訊。 此裝置監控單一負載的能耗，並控制高壓側，同時透過 Wi-Fi 將資料傳輸至其他裝置和雲端伺服器。該系統還包括一個返馳式電源供應單元 (PSU)，該單元能夠有效地為系統供電，同時又非常緊湊。
