The SGM2547 family is a compact electronic fuse (eFuse) with a full suite of protection functions. With very few external components, the SGM2547 can provide multiple protection modes: over-current, over-voltage, short-circuit and reverse current blocking.
The output current limit threshold and the transient over-current blanking timer can be adjusted by the user. The analog output load current is monitored by the ILIM pin. Programmable over-voltage protection is used to turn off the device if the IN rises over a threshold value and the downstream circuitry is not damaged by unintended power supply. Due to the back-to-back FETs packaged inside the chip, the SGM2547 can block reverse current from flowing through the channel when it is turned on, this function can be also disabled by pulling RCBCTRL pin (SGM2547CR only) low, 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.
The SGM2547 is available in a Green WLCSP- 2.5×1.79-12L package.
