EM6323LXSP5B-2.9+

Supervisors Overview

The EM6323LXSP5B-2.9+ is a reset circuit manufactured by EM Microelectronic, featuring manual reset and watchdog capabilities. It monitors supply voltage to generate reset signals after a fixed timeout period. The device operates within a voltage range of 1.5V to 5.5V and supports an operating temperature range from -40°C to +125°C. Key electrical parameters include an ultra-low supply current of 2.9μA at VDD=3.3V, a reset threshold accuracy of ±1.5%, and a threshold hysteresis of 2.1% of VTH. The part is available in small packages such as SC70-4L, SC70-5L, and SOT23-5L.

Supervisors Feature Summary

• Integrates manual reset input with internal pull-up for system control
• Provides watchdog functionality alongside standard voltage monitoring
• Ensures reliable operation with high reset threshold accuracy and hysteresis
• Designed for maximum flexibility in portable and battery-operated applications

Supervisors Applications

Supervisors Procurement Notes

Verify the exact suffix and package type when ordering, as variations exist within the EM6323 series. Confirm that the specific variant matches the required manual reset and watchdog features. Ensure compatibility with the target voltage range and temperature specifications. Cross-reference the datasheet for pinout and electrical characteristics to avoid integration errors. Check for any specific handling or storage requirements mentioned in official documentation.

Supervisors Selection Notes

Select this component when both manual reset and watchdog functions are necessary in a single IC. Consider the ultra-low supply current for battery life optimization. Evaluate the available package options against board space constraints. Ensure the reset threshold voltage aligns with the system's minimum operational voltage. Verify that the output configuration meets the interface requirements of the monitored system.

Supervisors Part Context

The EM6323 series belongs to EM Microelectronic's portfolio of ultra-low current reset circuits. These devices are designed for high flexibility across various end-applications. The series includes multiple configurations with different thresholds and output types. The EM6323LXSP5B-2.9+ specifically combines manual reset and watchdog features, distinguishing it from simpler reset-only variants in the family.

Supervisors Replacement Considerations

Check for other EM6323 variants with similar threshold voltages and feature sets. Verify package compatibility if substituting with a different pin count or outline. Ensure the replacement maintains the required manual reset and watchdog functionality. Compare supply current and operating temperature ranges to confirm equivalent performance.
