EM6325CYSP5B-4.6+

Supervisors Overview

The EM6325CYSP5B-4.6+ is an ultra-low current reset circuit manufactured by EM Microelectronic, designed for portable and battery-operated devices. It monitors supply voltage between 1.5V and 5.5V and generates a reset signal after a fixed timeout period once the voltage exceeds the threshold. This specific variant features a manual reset input with an internal pull-up resistor. Key electrical parameters 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 device offers immunity to short negative transients and guarantees valid reset down to 0.9V.

Supervisors Feature Summary

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

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage and output type matching. Confirm package availability and lead times directly with authorized distributors or the manufacturer. Ensure environmental compliance requirements align with project specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when ultra-low power consumption is critical for battery life extension in portable applications. Choose based on required reset threshold voltage and desired output configuration (push-pull or open-drain). Consider the manual reset feature if external hardware control over the reset state is necessary for system initialization or debugging purposes.

Supervisors Part Context

The EM6325 series comprises ultra-low power reset circuits available in various configurations and small packages like SC70 and SOT23. These circuits are engineered for maximum flexibility in end-applications requiring reliable power supply monitoring within a wide voltage range and extended temperature operation capabilities.

Supervisors Replacement Considerations

Check for other EM6325 variants with different threshold voltages or output types that may fit the design. Verify pinout compatibility and functional equivalence with alternative reset ICs from other manufacturers if sourcing constraints exist.
