The LMV7275-Q1 is a single rail-to-rail input low power comparator, characterized at supply voltages of 1.8 V, 2.7 V, and 5 V. It consumes as little as 9-µA supply current per channel while achieving a 800-ns propagation delay.

The LMV7275-Q1 is available in a SC-70 package. With these tiny packages, the PCB area can be significantly reduced. They are ideal for low voltage, low power, and space-critical designs.

The LMV7275-Q1 features an open-drain output stage that allows for wired-OR configurations. The open-drain output also offers the advantage of allowing the output to be pulled to any voltage up to 5.5 V, regardless of the supply voltage of the LMV7275-Q1, which is useful for level-shifting applications.

The LMV7275-Q1 is built with Texas Instruments' advance submicron silicon-gate BiCMOS process. It has bipolar inputs for improved noise performance, and CMOS outputs for lowest negative output swing.

TIDA-01421 — 用於無感測器位置量測的車用有刷馬達波紋電流計數器參考設計

隨著現代汽車中的小型馬達持續演進,對保留座椅、車窗、滑動車門、後視鏡、升降門與其他由馬達驅動之位置記憶的需求也隨之增加。現有解決方案利用連接至馬達本體的多個磁性感測器,為馬達控制模組提供回饋迴路。無感測器方法可為現有解決方案提供備援,在某些情況下,可省去對附有感測器馬達的需求。透過導入直列式電流感測訊號調整電路,無感測器方法變得越來越受歡迎。此參考設計提供的解決方案可輕鬆修改,以適用於許多控制位置量測的汽車馬達系統。
