SGM2523C/SGM2523D
Programmable Current Limit Switches
GENERAL DESCRIPTION
FEATURES
The SGM2523C/D are compact electronic fuses (eFuses)
with a complete set of protection functions. The wide
operating voltage range is specifically designed for
many popular DC buses. The devices provide ±10%
current limit accuracy which is suitable for a wide range
of system protection applications.
● Wide Input Voltage Range from 2.6V to 22V
with Surge up to 30V
● Low RDS(ON) for the Integrated Protection
Switch: 75mΩ
● Programmable Soft-Start Time
● Programmable Current Limit from 100mA to 1.2A
● ±10% Current Limit Accuracy at TJ = +25℃
● Short-Circuit Protection
The programmable soft-start time controls the slew rate
of the output voltage during the power-up procedure.
● OCP Hiccup Protections:
The devices protect input from undesired shorts and
transients coming from the output.
SGM2523C: Limited Current Mode
SGM2523D: Shutdown Mode
● Thermal Shutdown Options:
SGM2523C: Auto-Retry
The SGM2523C/D are available in a Green SOT-23-6
package and operate over a temperature range of
-40℃ to +125℃.
SGM2523D: Latch-Off
● Enable Interface Pin
● -40℃ to +125℃ Operating Temperature Range
● Available in a Green SOT-23-6 Package
