The S-77100/77101 Series is a power sequencer.

The S-77100 Series can output enable signals of 4 channels, and controls the external power supply circuit. The S-77100

Series turns on and off the enable signals successively by changing "H" and "L" of the ON pin.

The S-77101 Series can output enable signals of 3 channels, and controls the external power supply circuit. The S-77101

Series turns on the enable signals successively by changing the ON pin from "L" to "H", and turns off the enable signals

successively by changing OFF

_______

pin from "H" to "L".

The delay time for each enable signal can be set by the external capacitor.

Also, the small 8-Pin TSSOP or SNT-8A package makes high-density mounting possible.



Features

• Easy support for sequencing of multiple power supplies.
