S-8340A25AFT-T2-G

Overview

The S-8340A25AFT-T2-G is a voltage detector manufactured by ABLIC Inc., designed to monitor supply voltages and generate reset signals. It features an ultra-low current consumption mode, ensuring minimal power drain during standby or active operation. The device operates within a specified input voltage range, triggering the output when the monitored voltage falls below the preset threshold. It includes built-in delay circuits to prevent false resets caused by transient noise or slow voltage ramp-up times. The component is housed in a compact SOT-26 package, suitable for space-constrained portable electronics and battery-powered applications requiring precise voltage supervision.

Procurement Notes

Verify the specific threshold voltage and package variant against the official ABLIC datasheet before ordering. Confirm that the S-8340A25AFT-T2-G designation matches the required operating temperature range and output configuration for your design. Ensure compliance with RoHS standards if applicable to your manufacturing process. Cross-reference the pinout diagram with your PCB layout to avoid connection errors.

Selection Notes

Select this component when low quiescent current is critical for system efficiency. Consider the fixed threshold voltage of 2.5V to ensure it aligns with the minimum operating voltage of the downstream logic. Evaluate the need for the internal delay function to mitigate noise sensitivity. Compare performance metrics with alternative voltage supervisors from other manufacturers if specific timing characteristics are required.

Part Context

This part belongs to the S-8340 series of voltage detectors, which are widely used in consumer electronics for power management. ABLIC Inc. specializes in analog and mixed-signal semiconductors, providing reliable monitoring solutions. The S-8340 series is known for its precision and low power consumption, making it a standard choice for voltage supervision in modern embedded systems.

Replacement Considerations

Check for direct pin-to-pin replacements such as other S-8340 variants with different thresholds. Verify compatibility with similar voltage supervisors from competitors like Texas Instruments or Maxim Integrated. Ensure that any substitute maintains the same current consumption profile and delay characteristics to preserve system stability.
