A89500有刷直流驅動器
Allegro MicroSystems
Allegro的100V半橋閘極驅動器是專為具有高功率電感負載的應用而設計
Allegro的A89500適用於廣泛的汽車和商業應用,為12V和新興的48V電池系統提供通用架構。它是專為具有高功率電感負載的應用而設計,例如有刷 DC 馬達、螺線管、致動器。A89500是Allegro首款5.5V至100V額定工作電壓的80V半橋閘極驅動器。
A8500以高效致動器、馬達、數位放大器為目標,能夠以非常高的速度切換,同時提供出色的匹配。內部邏輯可防止閘極驅動輸出同時開啟,從而防止交叉導通。每個 MOSFET 均由相容於3.3V和5V邏輯的獨立邏輯位準輸入控制。
A89500可以透過第三個離散輸入,進入低功率睡眠模式。需要一個8V至15V的單電源來為閘極驅動器供電。
A8900可在使用半橋拓撲的分散式系統架構中實現備援,並減少系統覆蓋區。此元件採用極小的封裝,進一步縮小了面積。
