Seiko SII Power Sequencer S-77100/77101 Series

This series is specially designed to assure a stable startup of systems using microcontrollers, FPGA ( Fiel programmable Gate Array) or SoC (System On Chip) with multiple power supply pins.

Series *Enables easy control of the power sequence only by connecting an external capacitor *Minimizes the load to a power source due to the low current consumption of 3,0µA typ. (in a stable status). *Various selectable options such as input/output form to meet your diverse needs.
