EM6353BZ2SP3B-4.6+

Supervisors Overview

The EM6353BZ2SP3B-4.6+ is a reset circuit manufactured by EM Microelectronic-Marin SA, designed for power management applications. It monitors supply voltage and generates a reset signal when the threshold is exceeded. The device operates within a supply voltage range of 1.5V to 5.5V and features an ultra-low supply current of 2.9μA at VDD = 3.3V. It offers an adjustable reset timeout period via an external capacitor and provides three output types: active-low push-pull, active-low open-drain, and active-high push-pull. The circuit ensures correct output states down to 0.8V and includes 11 selectable reset threshold voltages ranging from 1.31V to 4.63V.

Supervisors Feature Summary

• Ultra-low supply current consumption suitable for battery-operated devices
• Adjustable reset timeout period using an external capacitor
• Three distinct output options including active-low push-pull and open-drain configurations

Supervisors Applications

• Portable electronic devices
• Battery-operated systems
• Microprocessor reset circuits

Supervisors Procurement Notes

Verify the specific suffix '4.6+' against official datasheets to confirm the exact reset threshold voltage selection. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Confirm package type availability matches design constraints. Cross-reference manufacturer documentation for any RoHS compliance updates or pinout variations in different revisions.

Supervisors Selection Notes

Select this component when a precise reset threshold near 4.6V is required for system stability. Consider the available output configurations to match interface requirements without additional logic. Evaluate the need for adjustable delay timing versus fixed internal delays found in other variants. Verify that the low standby current meets the power budget for the intended application.

Supervisors Part Context

This part belongs to the EM6353/EM6354 family of ultra-low current reset circuits. These components are engineered for flexibility in various end-applications up to 125°C. The family supports power supplies between 1.5V and 5.5V and utilizes small packages like SC70 and SOT23 to maximize board space efficiency.

Supervisors Replacement Considerations

Check for direct substitutes within the EM6353 series with different threshold voltages if the 4.6V setting is not strictly necessary. Verify pin-to-pin compatibility with other reset ICs from manufacturers offering similar ultra-low current specifications.
