1 / 40 page S-77100/77101 Series www.sii-ic.com POWER SEQUENCER © SII Semiconductor Corporation, 2015 Rev.1.0_01 1 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. • Delay time can be set by the external capacitor. • Sequence operations of 4 channels can be controlled by 1 input signal. (S-77100 Series) • On-sequence operation and off-sequence operation can be controlled by the separate input signal. (S-77101 Series) • Enable output can be increased by cascade connection. • Low current consumption: 3.0 μA typ. (Off period, power-good period, VDD = 3.3 V, Ta = +25°C) • Wide range of operation voltage: 2.2 V to 5.5 V • Operation temperature range: Ta = −40°C to +85°C • Output form is selectable: CMOS output, Nch open-drain output • Output logic is selectable: Active "H", active "L" • Lead-free (Sn 100%), halogen-free: Applications • Power sequencing for multiple devices • Sequencing for microprocessor and microcontroller • Power sequencing for FPGA • Power sequencing for TV, camera, printer, etc. Packages • 8-Pin TSSOP • SNT-8A |
