Allegro MicroSystems AHV85110隔離式GaNFET閘極驅動器

Allegro MicroSystems AHV85110隔離式GaNFET閘極驅動器為自供電的單通道隔離式驅動器。這些閘極驅動器設計用於驅動多種應用和拓撲中的GaNFET。AHV85110驅動器的供應電壓範圍為10.5V至13.2V、漏電距離為8.4 mm，具快速回應的啟用腳位，以及2.8Ω上拉和1Ω下拉的獨立驅動輸出腳位。AHV85110閘極驅動器具有50 ns傳播延遲和高峰值源極/汲極能力，能有效驅動高頻設計的GaN FET。這些閘極驅動器採用輕巧、薄型、表面黏著的10 mm x 7.66 mm x 2.41 mm NH封裝。AHV85110閘極驅動器非常適合EV充電器、車載充電器 (OBC)、AC-DC和DC-DC轉換器、交通運輸、機器人、微型變頻器、太陽能、工業和潔淨能源。

AHV85110閘極驅動器內含一個整合在驅動器中的隔離式輸出偏壓電源，因此不需要外部閘極驅動輔助偏壓電源或高側自舉。閘極驅動器具有快速傳播延遲和高峰值源極/汲極能力，能有效驅動高頻設計的GaN FET。

特點

Provide greater power and are more efficient by using 50% of the design footprint (PCB savings)
Eliminate bootstrap circuits and isolated supplies while minimizing common-mode capacitance, which reduces EMI filter design efforts and improves overall efficiency

Lower Bill Of Materials (BOM) count and production cost
Provide a reliable, scalable design process across platforms by removing the need to fully redesign a power module when working with multiple GaN FET suppliers
