EM6325CXSP5B-4.6+

Supervisors Overview

The EM6325CXSP5B-4.6+ is a reset circuit with manual reset functionality manufactured by EM Microelectronic. It monitors supply voltage between 1.5V and 5.5V, generating a reset signal after a fixed timeout when VDD rises above the threshold. The device features an ultra-low supply current of 2.9μA at 3.3V and operates within a temperature range of -40°C to +125°C. It offers ±1.5% reset threshold accuracy and includes a manual reset input (MR) with an internal pull-up resistor. The specific suffix indicates a 4.63V threshold voltage, active-low push-pull output, and SC70-5L package.

Supervisors Feature Summary

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

Supervisors Applications

• Portable electronic devices
• Battery-operated systems
• Microprocessor system supervision

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage, output type, and package style. Confirm RoHS compliance status if required for specific manufacturing standards. Check for alternative pinout configurations in similar packages to prevent integration errors during PCB design and assembly processes.

Supervisors Selection Notes

Select this component when precise voltage monitoring is required for systems operating between 1.5V and 5.5V. The manual reset feature is critical for applications requiring explicit system initialization control. Ensure the chosen threshold voltage matches the minimum operational voltage of the target microcontroller or logic circuit to guarantee reliable system startup and stability under varying power conditions.

Supervisors Part Context

This part belongs to the EM6325 series of ultra-low current reset circuits designed for maximum flexibility in end-applications. The series supports various threshold voltages and output options to accommodate different system requirements. Manufactured by EM Microelectronic, these components are optimized for portable and battery-powered devices where power efficiency and small form factors are paramount.

Supervisors Replacement Considerations

Consider EM6325 variants with different threshold voltages or output configurations from the same manufacturer. Verify compatibility with existing PCB footprints, specifically SC70-5L or SOT23-5L packages, before substituting. Ensure replacement parts maintain the same manual reset functionality and operating temperature range.
