EM6323LYSP5B-2.9+

Supervisors Overview

The EM6323LYSP5B-2.9+ is a reset circuit manufactured by EM Microelectronic, featuring manual reset and watchdog capabilities. It monitors supply voltage to generate appropriate reset signals after a fixed timeout period once the voltage exceeds the threshold. The device operates within a supply range of 1.5V to 5.5V and supports an operating temperature range from -40°C to +125°C. It offers high reset threshold accuracy of ±1.5% and includes threshold hysteresis of 2.1% of V_TH. The circuit provides active-low push-pull output and ensures valid resets down to 0.9V.

Supervisors Feature Summary

• Features a manual reset input that asserts reset when pulled low, utilizing an internal pull-up resistor for ease of integration.
• Generates a reset signal after a fixed timeout period upon power-up, allowing system stabilization before becoming fully active.
• Provides immunity to short negative supply voltage transients to maintain reliable operation during power fluctuations.
• Ensures guaranteed reset validity down to 0.9V, supporting stable system initialization at low voltage levels.

Supervisors Applications

• Portable electronic devices requiring ultra-low current consumption
• Battery-operated systems needing reliable power monitoring
• Embedded controllers requiring manual reset functionality
• Automotive electronics operating in extreme temperature environments

Supervisors Procurement Notes

Verify the exact suffix '2.9+' corresponds to the specific threshold voltage and package configuration required for your design. Confirm RoHS compliance status with the supplier. Ensure the operating voltage range matches your system's supply rails. Check for any specific handling requirements due to the small package type. Validate the reset timeout period against your system's startup sequence needs.

Supervisors Selection Notes

Select this component when a combination of manual reset control and automatic power-on reset is necessary. Consider its ultra-low supply current for battery-sensitive applications. Evaluate the ±1.5% threshold accuracy against your system's voltage tolerance requirements. Verify compatibility with the available package options such as SC70 or SOT23 variants. Assess the need for transient immunity in noisy electrical environments.
