EM6325CYSP5B-2.9+

Supervisors Overview

The EM6325CYSP5B-2.9+ is an ultra-low current reset circuit manufactured by EM Microelectronic, designed for portable and battery-operated devices. It monitors supply voltage and generates a reset signal after a fixed timeout period once the threshold is exceeded. The device features a manual reset input with an internal pull-up resistor. Key specifications include an operating temperature range of -40°C to +125°C, a typical supply current of 2.9µA at 3.3V, and a reset threshold accuracy of ±1.5%. The specific suffix indicates a 2.93V threshold voltage.

Supervisors Feature Summary

• Ultra-low supply current consumption suitable for battery-powered applications
• Manual reset function with internal pull-up resistor
• Immune to short negative supply transients
• Guaranteed valid reset output down to low voltage levels

Supervisors Applications

• Portable electronic devices
• Battery-operated systems
• Embedded system power monitoring
• Voltage supervision in microcontroller circuits

Supervisors Procurement Notes

Verify that the ordering suffix corresponds to the required reset threshold voltage, as the EM6325 series offers multiple voltage options. Confirm the package type matches the design constraints, typically SC70-4L, SC70-5L, or SOT23-5L. Ensure the active-low push-pull output configuration aligns with the target system logic requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a precise reset threshold near 2.93V is required for systems operating between 1.5V and 5.5V. Consider the manual reset capability if external hardware reset control is necessary. Evaluate the package size against available PCB space, noting the availability of small form factors like SC70 and SOT23 for compact designs.

Supervisors Part Context
