GENERAL DESCRIPTION

The SGM2536 family is a compact electronic fuse

(eFuse) with a full suite of protection functions. With

precision current limit, the device can provide excellent

accuracy and be well applied to many system

protection applications. The output current limit

threshold and the transient over-current blanking timer

can be adjusted by the user. Due to the back-to-back

FETs packaged inside the chip, the SGM2536 allows

bidirectional current to flow through the channel when it

is turned on, but prohibits bidirectional current flow

when it is turned off, which is very suitable for USB

OTG. The VOUT rise time can be programmed by setting

an additional capacitor to the SS pin, which can

minimize inrush current. Programmable over-voltage

protection is used to turn off the device if the IN raises

over a threshold value and the downstream circuitry is

not damaged by unintended power supply.

The SGM2536 is available in a Green TQFN-2×2-10L

package
