具有電流調(diào)節(jié)功能的 DRV120 單通道繼電器、電磁閥、低側(cè)驅(qū)動(dòng)器

DRV120 是一款針對(duì)螺線管的 PWM 電流驅(qū)動(dòng)器。 它被設(shè)計(jì)成使用控制良好的電流來調(diào)節(jié)電流以確保激活并同時(shí)減少功率耗散。 螺線管電流快速斜升以確保閥門或者繼電器的打開。 在最初的斜升后，螺線管電流被保持在峰值以確保正確運(yùn)行，這之后，為了避免過熱問題并減少功率耗散，這個(gè)電流被減少至較低的保持水平。使用一個(gè)外部電容器對(duì)峰值電流的持續(xù)時(shí)間進(jìn)行設(shè)定。 電流斜波峰值和保持電平、以及 PWM 頻率可由外部電阻器獨(dú)立設(shè)定。 如果針對(duì)相應(yīng)參數(shù)的默認(rèn)值適用于應(yīng)用的話，外部設(shè)置電阻器也可被省略。 DRV120 可由 6V 至 28V 的外部電源供電運(yùn)行。 ? 用于控制螺線管電流的帶有脈寬調(diào)制 (PWM) 的集成金屬氧化物半導(dǎo)體場(chǎng)效應(yīng)晶體管 (MOSFET) \n? 螺線管電流的快速斜升以保證激活\n? 可外部設(shè)定峰值電流、峰值電流的保持時(shí)間、保持電流和 PWM 時(shí)鐘頻率。 它們還可以在無需外部組件的情況下在標(biāo)稱值上運(yùn)行。\n? 高達(dá) 28V 的外部電源電壓\n? 保護(hù) \n? 欠壓閉鎖 (UVLO)\n? 可選狀態(tài) (STATUS) 輸出\n? 運(yùn)行溫度范圍：-40oC 至 105oC\n? 8 引腳和 14 引腳 薄型小外形尺寸 (TSSOP) 封裝選項(xiàng);
