- **Temperature Stability:** Reliable performance across -40°C to +85°C.  
- **CMOS Output:** Ensures compatibility with digital circuits.  

This information is based on SEIKO's official documentation for the **S-8491CUP-DKC-T2** voltage detector IC.

Application Scenarios & Design Considerations

BATTERY PROTECTION IC

Alternative Part Number

  • S-80845CLMC-B6AT2U --: ABLIC (formerly Seiko Instruments) voltage detector in the same S-808xx family with similar reset/detection function and package, direct successor lineage.
  • MAX809REUR+T --: Widely available 3-pin microprocessor reset supervisor with comparable threshold and active-low reset behavior, good functional drop-in for many Seiko S-8491 applications.
  • MCP131T-300E/TO --: Low-cost 3-pin voltage supervisor with similar reset output and threshold range, suitable alternative when exact Seiko part is unavailable.
  • S-8491CUP-DKC-T2 --: placeholder
