S-80957CNPF-G9TTFU

Supervisors Overview

The S-80957CNPF-G9TTFU is a voltage detector from the ABLIC S-809 series, designed for supervisory circuit applications. It operates within a supply voltage range of 1.6 V to 10 V and features an adjustable reset delay time controlled by an external capacitor. The device provides an active low CMOS output with a threshold accuracy of ±2%. It consumes a typical operating current of 1.1 µA and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a compact SNT-4A-4 package.

Supervisors Feature Summary

• Supports adjustable reset delay timing via an external capacitor connection
• Delivers an active low CMOS output signal for system monitoring
• Maintains high detection accuracy with ±2% threshold tolerance
• Operates with ultra-low power consumption suitable for battery-powered devices

Supervisors Applications

• Portable electronic equipment requiring extended battery life
• Microprocessor and microcontroller system reset circuits
• Battery backup switching systems
• General-purpose voltage supervision in embedded systems

Supervisors Procurement Notes

Verify the specific suffix G9TTFU against official ABLIC documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with the target application's voltage range and required reset delay characteristics before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when an adjustable reset delay is required rather than a fixed internal delay. Compare the S-809 series specifications against other ABLIC voltage detectors to ensure the 1.1 µA current consumption and 10 V maximum input voltage meet the design constraints. Verify that the SNT-4A-4 package footprint aligns with the PCB layout requirements.

Supervisors Part Context

This part belongs to the S-809 series of voltage detectors manufactured by ABLIC Inc. The series is characterized by low current consumption and flexible configuration options, including adjustable delays. The S-809 series serves as a key solution for power management ICs in portable electronics, offering reliable supervision with minimal impact on overall system power efficiency.

Supervisors Replacement Considerations

Check for direct substitutes within the S-809 series with different threshold voltages or delay configurations. Evaluate alternative packages such as SC-82AB if pin compatibility allows. Consult ABLIC obsolescence notices to ensure long-term availability of the SNT-4A-4 package variant.
