EM6354XSP5B-2.9+

Supervisors Overview

The EM6354XSP5B-2.9+ is an ultra-low current reset circuit manufactured by EM Microelectronic-Marin SA, designed for power supply monitoring in electronic systems. It generates a reset signal when the supply voltage drops below a specific threshold, ensuring system functionality. The device features an adjustable reset timeout period via an external capacitor and offers three output configurations: active-low push-pull, active-low open-drain, and active-high push-pull. It operates with supply voltages between 1.5V and 5.5V and maintains correct output states down to 0.8V. The circuit provides ±1.5% reset threshold accuracy and includes 11 selectable threshold voltages ranging from 1.31V to 4.63V.

Supervisors Feature Summary

• Adjustable reset timeout period using an external capacitor
• Ultra-low supply current of 2.9µA at VDD = 3.3V
• Three reset output options including active-low push-pull, active-low open-drain, and active-high push-pull
• High reset threshold accuracy of ±1.5%

Supervisors Applications

• Portable devices requiring low power consumption
• Battery-operated equipment needing reliable power management
• Electronic systems requiring automatic restart after power up

Supervisors Procurement Notes

Verify the exact suffix 'XSP5B-2.9+' against official EM Microelectronic documentation to confirm pinout, package type (typically SOT23 or SC70), and specific threshold voltage selection. Ensure compatibility with your system's voltage range and reset timing requirements before procurement.

Supervisors Selection Notes

Select this component when an adjustable delay is required for system stabilization. Consider the available threshold voltages and output types to match your microprocessor or logic interface needs. Verify that the operating temperature range (-40°C to +125°C) suits your application environment.

Supervisors Part Context

This part belongs to the EM6354 series of ultra-low power reset circuits. It is designed for flexibility in various end-applications, offering small package options like SC70 and SOT23. The series is known for its low supply current and wide operating voltage range, making it suitable for portable and battery-powered devices.

Supervisors Replacement Considerations

Check for direct substitutes within the EM6354 family with different threshold voltages or output configurations. Other manufacturers' reset circuits with similar adjustable delay and low current specifications may be compatible if pinouts and electrical characteristics align.
