LTC4354 的典型應用是一款負電壓二極管 OR 控制器,用于驅動兩個外部 N 溝道 MOSFET。它取代了兩個肖特基二極管和相關的散熱器,從而節省了功耗和面積。使用 N 溝道 MOSFET 作為傳輸晶體管,大大降低了功耗
說明
Typical Application for LTC4354 is a negative voltage diode-OR controller that drives two external N-channel MOSFETs. It replaces two Schottky diodes and the associated heat sink, saving power and area. The power dissipation is greatly reduced by using N-channel MOSFETs as the pass transistors
