MX25924 Datasheet | MAXINMICRO

DESCRIPTION The MX25924 family of electronic fuses are highly integrated circuit protection and power management solutions in small packages. The device uses very few external ponents and offers multiple protection modes. They are effective against overloads, short circuits, voltage surges, excessive inrush - Hard Disk Drives (HDD) and Solid State Drives (SSD) - Set-top box - Server/auxiliary (AUX) power - Fan control - PCI/PCIe cards GENERAL INFORMATION currents and reverse currents. The current limit level can be programmed with an external resistor. The MX25924 has an internal clamp circuit limits overvoltage to a safe fixed maximum value without the need for external ponents. Applications with special voltage ramp requirements can use a single capacitor to program d Vd T to ensure the proper output ramp rate. Many systems, such as SSDs, prohibit backflow of stored capacitive energy through FET diodes to a buck or shorted input bus. The BFET pins are dedicated to this type of system. External N channel FETs can form a "back-to-back (B2B)" connection with the MX25924 outputs, and the gate driven by the BFET prevents current from flowing from the load back to the supply.
