E-Fuse MX5069 High-Side N_FET Driver Efficiently Manage Power Distribution For 24V And 48V Industrial Systems

The MX5069 high-side N_FET driver works with an external MOSFET and acts as an ideal diode rectifier when connected in series with the power supply. This controller enables MOSFETs to replace diode rectifiers in power distribution networks,reducing power loss and voltage drop. The MX5069 controller provides charge pump gate drive for an external N- channel MOSFET and fast response comparator to turnoff the FET when current flows in reverse.The current limit in the external series pass N-Channel.MOSFET are programmable. The input undervoltage and overvoltage lockout levels are programmabled by resistance divider networks. The MX5069 automatically restarts at a fixed duty cycle. MX5069 is available in 10-pin DFN3*3 and MSOP10Lpackage.
