EM6325AXSP5B-2.9+

Supervisors Overview

The EM6325AXSP5B-2.9+ is an ultra-low current reset circuit manufactured by EM Microelectronic. It monitors supply voltage and generates a reset signal after a fixed timeout period, ensuring system stability during power-up. The device operates within a supply voltage range of 1.5V to 5.5V and features a manual reset input with an internal pull-up resistor. It offers a standard 200ms reset timeout and maintains an ultra-low supply current of 2.9µA at 3.3V. The component provides ±1.5% threshold accuracy and includes threshold hysteresis of 2.1% of V_TH. It guarantees valid reset down to 0.9V and is immune to short negative transients.

Supervisors Feature Summary

• Ultra-low supply current consumption for battery-operated applications
• Manual reset function with internal pull-up resistor
• High reset threshold accuracy with built-in hysteresis
• Immunity to short negative supply voltage transients

Supervisors Applications

• Portable electronic devices requiring low power consumption
• Battery-operated systems needing reliable power monitoring
• Embedded systems requiring stable reset signals during startup

Supervisors Procurement Notes

Verify the specific suffix AXSP5B-2.9+ against official datasheets to confirm the exact threshold voltage and package configuration. Ensure compatibility with the target operating temperature range of -40°C to +125°C. Confirm that the required reset output polarity matches the available options in the official documentation before procurement.

Supervisors Selection Notes

Select this component when an ultra-low quiescent current is critical for extending battery life. The fixed 200ms timeout suits applications where system stabilization time is predictable. Consider the ±1.5% accuracy requirement for precise voltage monitoring needs. Verify that the SOT23-5L package fits the design constraints.

Supervisors Part Context

This part belongs to the EM6325 family of reset circuits designed for flexibility in various end-applications. The family supports multiple threshold voltages and package types, including SC70 and SOT23 variants. The EM6325 series is engineered for high reliability in portable and battery-powered environments up to 125°C.

Supervisors Replacement Considerations

Check for other EM6325 variants with different threshold voltages or output configurations if the exact pinout or voltage level does not match. Cross-reference with similar ultra-low power reset ICs from other manufacturers only if electrical specifications align perfectly.
