EM6325CXSP5B-2.6+

Supervisors Overview

The EM6325CXSP5B-2.6 is an ultra-low current reset circuit manufactured by EM Microelectronic-Marin SA, designed for portable and battery-operated devices. It monitors supply voltage between 1.5V and 5.5V, generating a reset signal after a fixed timeout when VDD rises above the threshold. This specific variant features a manual reset input (MR) with an internal pull-up, a 200ms reset timeout period, and a 2.63V reset threshold voltage. It operates within a temperature range of -40°C to +125°C with ±1.5% accuracy and consumes only 2.9μA at 3.3V.

Supervisors Feature Summary

• Manual reset function via dedicated MR input
• Ultra-low supply current consumption
• Immunity to short negative transients
• Guaranteed valid reset down to low voltage levels

Supervisors Applications

• Portable electronic devices
• Battery-operated systems
• Microprocessor reset circuits
• Embedded system power management

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage, output type, and package selection. Confirm that the manual reset feature is required for the specific application design. Check for any updated revision notes or alternative pinout configurations from the manufacturer before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 200ms delay and manual reset capability are required. The 2.63V threshold suits systems operating near this voltage level. Ensure the SC70-4L package fits the board space constraints. Consider the 2.9μA quiescent current impact on overall battery life in low-power designs compared to higher-current alternatives.

Supervisors Part Context

This part belongs to the EM6325 family of reset circuits, which offers various threshold voltages and output options. The CXSP5B suffix indicates specific electrical characteristics including the 2.63V threshold and push-pull active-low output. The family is known for small packages and flexibility in end-applications requiring reliable power monitoring.

Supervisors FAQ

What is the purpose of the MR pin?

The MR pin allows for manual assertion of the reset signal when pulled low, providing external control over the system reset state.

How does the device handle voltage drops below the threshold?

The circuit generates a reset signal when VDD falls below the 2.63V threshold, ensuring system stability during brown-out conditions.
