Dual Load Detectors with 300nA Operating Current

The SGM790A, SGM790B and SGM790C are low current, dual load sensing devices that can detect connection or removal of the loads on a supply bus. By using short pulse injections into the input capacitance and measuring the voltage change, load existence is periodically checked.

The SGM790A and SGM790C provide wake-up output pins, denoted by WKP and nWKP respectively. The logic levels of the SGM790C are completely the opposite of the SGM790A. When a load attachment or detachment is sensed, a pulse (1.3s, TYP) is generated on WKP (nWKP) pin to report the status change or to awaken the host. The bidirectional WKP (nWKP) pin is also used as a selection input pin to choose either SNS1 or SNS2 channel. The detection status of SNSx channel is reported on the FLG output pin during the 1.3s window. In the SGM790B, the most recent detection status of SNSx channel is reported on the corresponding FLGx channel output.

These devices are available in a Green UTDFN-1.2× 1.2-6L package, and can operate in the ambient temperature range of -40℃ to +85℃.
