一般說明：MAX1978ETM+T
MAX1978ETM+T/MAX1979 是最小、最安全、最精確完整的單片溫度控制器，用于帕爾貼熱電冷卻器 (TEC) 模塊。片上電源FET 和熱控制回路電路最大限度地減少了外部組件，同時保持高效率。可選擇500kHz/1MHz 開關頻率和獨特的紋波消除方案優化了組件尺寸和效率在降低噪音的同時。內部開關速度MOSFET 經過優化以降低噪聲和 EMI。超低漂移斬波放大器保持 ±0.001°C 溫度穩定。直接控制輸出電流而不是電壓以消除電流浪涌。單獨加熱和冷卻電流和電壓限制提供了最高水平的TEC保護。
MAX1978ETM+T 采用單電源供電，提供通過在輸出之間偏置 TEC 來實現雙極 ±3A 輸出兩個同步降壓穩壓器。真正的雙極操作在低負載電流下控制溫度而沒有“死區”或其他非線性。控制系統不當設定點非常接近自然操作時進行搜索點，只有少量的加熱或冷卻需要。模擬控制信號精確設置 TEC當前的。 MAX1979 提供高達 6A 的單極性輸出。提供一個斬波穩定儀表放大器和一個高精度積分器放大器來創建一個比例積分 (PI) 或比例積分微分 (PID)控制器。儀表放大器可以連接到一個外部 NTC 或 PTC 熱敏電阻、熱電偶或半導體溫度傳感器。模擬輸出提供給監測TEC溫度和電流。此外，分開過熱和欠溫輸出指示當 TEC 溫度超出范圍時。片上參考電壓為熱敏電阻橋提供偏置。
MAX1978ETM+T/MAX1979 采用薄型48 引腳薄型 QFN-EP 封裝，指定在-40°C 至 +85°C 溫度范圍。熱的帶外露金屬焊盤的增強型 QFN-EP 封裝最大限度地降低工作結溫。評估套件可用于加速設計。
