The LM2903B-Q1 device is the next generation version of the industry-standard LM2903-Q1 comparator family. This next generation family provides outstanding value for cost-sensitive applications, with features including lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2kV ESD performance with drop-in replacement convenience.

All devices consist of two independent voltage comparators that are designed to operate over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is within 2V to 36V, and VCC is at least 1.5V more positive than the input common-mode voltage. The outputs can be connected to other open-collector outputs.

The LM2903-Q1 and LM2903B-Q1 are qualified for the AEC-Q100 Grade 1 temperature range of -40°C to +125°C. The LM2903E-Q1 is Qualified for the Grade 0 extended temperature range of -40°C to +150°C.

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。  (...)
