EM6353BX2SP3B-4.4+

Supervisors Overview

The EM6353BX2SP3B-4.4+ is a reset circuit manufactured by EM Microelectronic-Marin SA, designed for portable and battery-operated devices. It monitors supply voltage to generate appropriate reset signals, ensuring system functionality within power supplies between 1.5V and 5.5V. The device features an ultra-low supply current of 2.9μA at VDD=3.3V and operates across a temperature range of -40°C to +125°C. It offers ±1.5% reset threshold accuracy with 11 selectable threshold voltages, including the specific 4.4V option indicated in the model suffix. The output configuration is active-high push-pull, and the timeout period is adjustable via an external capacitor.

Supervisors Procurement Notes

Verify the exact package type and output configuration against the manufacturer's datasheet before procurement. Confirm that the selected reset threshold voltage aligns with the system's minimum operating voltage requirements. Ensure the external capacitor value used for timeout adjustment falls within the specified operational limits to guarantee correct reset behavior under all conditions.

Supervisors Selection Notes

Select this component when low power consumption is critical for extending battery life in portable electronics. Choose the specific model variant based on the required reset threshold voltage and desired output polarity (active-high or active-low). Consider the operating temperature range and package size constraints to ensure compatibility with the target application environment and PCB layout requirements.

Supervisors Part Context
