EM6354XSP5B-1.8+

Supervisors Overview

The EM6354XSP5B-1.8+ is an ultra-low current reset circuit manufactured by EM Microelectronic-Marin SA. It monitors supply voltage and generates a reset signal when VDD drops below the threshold, ensuring system stability. The device operates with power supplies between 1.5V and 5.5V and features an adjustable reset timeout period using an external capacitor. It offers three output types: active-low push-pull, active-low open-drain, and active-high push-pull. The circuit guarantees correct output states down to 0.8V and provides 11 selectable reset threshold voltages, including 1.8V.

Supervisors Feature Summary

• Ultra-low supply current consumption for battery-operated applications
• Adjustable reset timeout period via external capacitor
• Multiple output configuration options including push-pull and open-drain
• High accuracy reset threshold with wide operating temperature range

Supervisors Applications

• Portable electronic devices requiring low power management
• Battery-operated systems needing reliable voltage monitoring
• Embedded systems requiring stable reset signals during power fluctuations

Supervisors Procurement Notes

Verify the specific suffix 'XSP5B-1.8+' against official datasheets to confirm the package type and exact threshold voltage. Ensure compatibility with the target application's voltage range and output requirements. Check for RoHS compliance and lead-free status if required by manufacturing standards. Confirm availability of the SC70 or SOT23 package variant as specified in the ordering information.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for extending battery life. Choose based on the required reset threshold voltage from the available 11 options. Consider the output drive capability and polarity (active-high/low) needed for the connected microcontroller or logic interface. Evaluate the need for an adjustable delay time versus fixed timing solutions.

Supervisors Part Context

The EM6354 series belongs to EM Microelectronic's portfolio of ultra-low current reset circuits designed for maximum flexibility in end-applications up to 125°C. These circuits are optimized for portable and battery-operated devices, offering small packages like SC70 and SOT23. The series supports various threshold voltages and output configurations to suit diverse system requirements.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the EM6354 family with different thresholds or output types. Verify that any substitute maintains the same ultra-low current specifications and operating voltage range. Ensure the replacement supports the required reset delay adjustment method.
