GENERAL DEscriptION

The SGM2566A and SGM2566B are single channel load switches. The switches operate from a wide range of 0.8V to 5.3V (≤ VBIAS) supply voltage, and are controlled by the EN/nFAULT pin. The VOUT rise time can be programmed by setting an additional capacitor to the SS pin. They can provide a 6A maximum continuous switch current.

A 17mΩ low RDSON N-MOSFET is integrated. The small size and current make the device very suitable for space limited, battery-powered applications.

A number of protection features are provided in the device including soft-start, reverse-voltage protection and thermal shutdown. The SGM2566A has quick output discharge function in disable status.

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