S-80943CNNB-G9DT2G

Supervisors Overview

The S-80943CNNB-G9DT2G is a voltage detector from the S-809xxC series manufactured by ABLIC Inc. It features a single monitoring channel with an open-drain or open-collector output and active-low reset signal. The device has a fixed threshold voltage of 4.3V and a minimum reset timeout of 20ms. It operates within a temperature range of -40°C to 85°C and is housed in a SC-74A (SOT-753) surface-mount package.

Supervisors Feature Summary

• Provides precise voltage supervision for single-channel power monitoring applications
• Features open-drain/open-collector output compatible with various logic families
• Ensures system stability with a defined minimum reset timeout period

Supervisors Applications

• Portable electronic devices requiring battery voltage monitoring
• Embedded systems needing reliable power-on reset signals
• Industrial control circuits operating in wide temperature ranges

Supervisors Procurement Notes

Verify the specific suffix G9DT2G against official datasheets to confirm pinout and marking codes. Confirm RoHS compliance status as per current manufacturer statements. Check availability through authorized distributors as standard stock may be limited. Ensure the ordering part number matches the required package type SC-74A/SOT-753.

Supervisors Selection Notes

Select this component when a fixed 4.3V threshold is required for system supervision. Consider the open-drain output configuration for level shifting needs. Evaluate the SOT-753 package size for space-constrained designs. Verify that the 20ms minimum reset timeout meets the target application's startup requirements.

Supervisors Part Context

This part belongs to the S-809xxC series of voltage detectors, designed for low-power consumption and high accuracy. The series offers various threshold voltages and packages to suit different power management needs. The S-80943 variant specifically targets applications requiring a 4.3V detection level.

Supervisors Replacement Considerations

The S-80943CNMC-G9DT2U is listed as a parameter-equivalent substitute. Verify package compatibility between CNNB and CNMC suffixes before substitution.
