SGM791A

Single Load Detector

with 300nA Operating Current

GENERAL DESCRIPTION

FEATURES

The SGM791A is a low current, single load sensing

device that can detect connection or removal of the

load on a supply bus. By using short pulse injections

into the input capacitance and measuring the voltage

change, load existence is periodically checked.

● 2.5V to 5.5V Operating Voltage Range

● Very Low Operating Current: 300nA (TYP)

● Internal PFET Open-Drain Output

● 160ms Detection Period

● Available in a Green UTDFN-1×1-4L Package

The most recent detection status of the SNS pin can be

reported on the FLG output.

APPLICATIONS

The device is available in a Green UTDFN-1×1-4L

package. It operates in the ambient temperature range

of -40℃ to +85℃.
