S-8337ABHC-T8T1G

Overview

The S-8337ABHC-T8T1G is a voltage detector manufactured by ABLIC Inc., designed to monitor supply voltages and generate reset signals. This specific variant features an active-low output configuration with a fixed detection threshold voltage of 2.90V. It operates within a wide supply voltage range from 0.4V to 6.5V, ensuring compatibility with various low-voltage digital systems. The device incorporates a built-in delay timer to prevent false resets during power-up sequences, enhancing system reliability. Packaged in an ultra-small UCN-8C-0.4x0.4-4B format, it offers high integration for space-constrained applications.

Feature Summary

• Active-low output signal generation upon voltage drop below the detection threshold
• Built-in delay timer function to ensure stable operation during power transitions
• Ultra-small footprint packaging optimized for dense circuit board layouts

Applications

• Microcontroller reset circuits in portable electronic devices
• Battery-powered system monitoring and protection
• Low-voltage digital logic interface supervision

Procurement Notes

Verify the exact detection threshold voltage and output polarity against the official datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure the supply voltage remains within the specified limits to maintain accurate detection performance. Cross-reference the package dimensions with the mechanical drawing to guarantee physical compatibility with the PCB design.

Selection Notes

Choose this component when a precise 2.90V detection threshold is required for active-low reset signaling. Consider the ultra-small package size if board space is limited. Evaluate the need for internal delay functionality to handle power-up transients without external components. Compare alternative thresholds if the system voltage profile differs significantly from 2.90V.

Part Context

This part belongs to the S-8337 series of voltage detectors from ABLIC Inc., which are engineered for reliable power management in modern electronics.
