High-Side N_FET Driver MX5069 with 5V to 85V Wide Operating Range, Can Replace Diode Rectifiers in Power Distribution Networks
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 a charge pump gate drive for an external N-channel MOSFET and a fast response comparator to turn off the FET when the current flows in reverse.
The current limit in the external series pass N-Channel MOSFET is programmable. The input undervoltage and overvoltage lockout levels are programmed by resistance divider networks. The MX5069 automatically restarts at a fixed duty cycle. MX5069 is available in 10-pin DFN3*3 and MSOP10L package.
