S-80819CNMC-B8ET2G

Supervisors Overview

The S-80819CNMC-B8ET2G is a voltage detector manufactured by ABLIC Inc. It operates within a supply voltage range of 0.7 V to 5.5 V and features a fixed detection threshold of 1.9 V. The device utilizes CMOS technology to achieve super-low current consumption, typically 1.3 μA at 1.5 V for detection voltages up to 1.4 V, and 0.8 μa at 3.5 V for thresholds of 1.5 V or higher. It provides an open-drain output and is housed in an SOT-23-5 package.

Supervisors Feature Summary

• Utilizes CMOS technology for high integration and low power operation
• Features super-low current consumption suitable for battery-powered applications
• Provides an open-drain output signal for system monitoring

Supervisors Applications

• Battery-operated electronic devices requiring voltage supervision
• Portable consumer electronics with strict power constraints
• Embedded systems needing reliable undervoltage detection

Supervisors Procurement Notes

Verify the specific suffix B8ET2G against official ABLIC documentation to confirm pinout configuration and output type. Ensure compatibility with target PCB footprint SOT-23-5. Cross-reference datasheet revisions for any changes in electrical characteristics or recommended operating conditions before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 1.9 V detection threshold is required. Consider the SOT-23-5 package size constraints. Evaluate the 1.3 μA typical current consumption against system sleep current budgets. Confirm that the open-drain output interface matches the microcontroller or logic input requirements of the design.

Supervisors Part Context

This part belongs to the S-808XXC series of voltage detectors from ABLIC Inc., designed for portable equipment. The series emphasizes low power consumption and compact packaging. The S-80819 variant specifically sets the detection voltage at 1.9 V, distinguishing it from other thresholds in the family.

Supervisors Replacement Considerations

Check for direct substitutes within the S-808XXC series with different detection voltages if 1.9 V is not critical. Verify pin-to-pin compatibility with other SOT-23-5 voltage supervisors from ABLIC or other manufacturers offering similar low-power CMOS architectures.
