For all new designs with TPS3820-xx-Q1, use the TPS3820-xxQPDBVRQ1 part number. The TPS3820-xxQP is functionally equivalent and a replacement to the TPS3820xxQ. The TPS3820-xxQDBVRQ1 is not recommended for new designs (NRND).
The TPS382x-xx-Q1 family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains below the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to verify a proper system reset. The delay time, td, starts after VDD has risen above the threshold voltage VIT−. When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider. The TPS382x-xx-Q1 family also offers watchdog time out options of 200ms (TPS3820-xx-Q1) and 1.6s (TPS3823/4/8-xx-Q1).

TPS382-Q1EVM — 具有整合式看門狗的 TPS382x-Q1 電壓監控器評估模組
TIDA-00143 — 汽車 60W 無刷 DC (BLDC) 馬達驅動
這款 TIDA-00143 參考設計為 BLDC 馬達控制器，並採單一 12V（額定）電源供應器運轉設計，該電源供應器可隨一般汽車應用的廣泛電壓改變。 電路板的設計可驅動 60W 範圍內的馬達，這需要 5 安培的電流。 電路板的尺寸和佈局旨在協助評估驅動電子裝置和韌體，並可輕鬆存取個別測試點的重要訊號。 可透過使用 3 接點連接器，或是將馬達相線焊接到電路板上的電鍍通孔，以連接至各種馬達。 12Vdc 電源裝有保險絲，以防止在測試期間發生馬達故障時，造成電路板或工作台電源供應器損壞。 馬達的命令和狀態可透過標準 JTAG 連接器傳達，或是透過 PWM 輸入和輸出訊號傳達。 (...)
