SGM2538

The SGM2538 series of eFuses feature comprehensive protection functions, robust operation, accurate limit threshold and compact package which are very suitable for various system applications. The SGM2538 provides fixed over-voltage clamp (OVC), adjustable over-current protection (OCP) and fast short-circuit protection (SCP). The device also provides adjustable soft-start (SS) function to manage inrush current through external resistor. When the device junction temperature exceeds +155 ℃ , the thermal shutdown function works and turns off the device. For SGM2538BA, the device is designed with 170ms auto-retry after the TJ drops to TSD - 20℃. The auto-retry will repeat until the fault is removed. Besides the above features, the SGM2538 has additional configurable functions using the BFET pin. The BFET pin can be used to drive an external N-FET connected back to back with the internal pass FET to provide reverse current block (RCB) function. It can also be used as fault event indicator through an external transistor. The SGM2538 is available in a Green TDFN-3×3-10AL package.
