描述 Description

The SGM2566A and SGM2566B are single channel load switches that provide configurable rise time to minimize inrush current. The load switch contains an N-MOSFET that can operate over an input voltage range of 0.8V to 5.3V (≤ VBIAS) and can support a maximum continuous current of 6A. Each of switches is controlled by an on and off input (EN/nFAULT), which is capable of interfacing directly with low-voltage control signals. In the SGM2566A, a 265Ω on-chip load resistor is added for quick output discharge when switch is turned off.

The SGM2566A and SGM2566B are available in a Green TDFN-2×2-8L package. They are rated over the -40℃ to +105℃ temperature range.
