SGM2538

12V Electronic Fuse (eFuse) with

OVP Function and Blocking FET Control

GENERAL DESCRIPTION

FEATURES

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.

● Wide Input Voltage Range from 4.5V to 13.8V

with Surge up to 20V

● On-Resistance: 27mΩ (TYP)

● Programmable Current Limit: 1A to 5A

● ±8% I_LIMITAccuracy at 3.7A

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 T_Jdrops to T_SD- 20℃. The

auto-retry will repeat until the fault is removed.

● Reverse Current Blocking Support

● Programmable OUT Slew Rate, UVLO

● Built-in Thermal Shutdown

● Fixed Over-Voltage Clamp: 15V (SGM2538BA)

● Fault Response: Auto-Retry (SGM2538BA)

● Available in a Green TDFN-3×3-10AL Package

APPLICATIONS

PCIE SSD

Severs and Block Supplies

Motherboard Power Management

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.
