MAX6348XR38-T

Overview

The MAX6348XR38-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold of 3.8 V. The device provides an active low, open drain output with a standard reset delay time of 280 ms. It consumes a maximum operating supply current of 500 nA and maintains an accuracy of 1.5%. The component is housed in a compact SC-70-3 package and is rated for operation between -40°C and +85°C.

Feature Summary

Ultra-low power consumption suitable for battery-operated applications
Compact surface-mount packaging for space-constrained designs
Fixed factory-set reset threshold for simplified integration

Applications

Portable electronic devices requiring extended battery life
Microprocessor system power monitoring
Battery-powered instrumentation

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout and electrical characteristics. Ensure the ordering code matches the required threshold voltage and package type. Confirm availability status as distribution channels may vary. Cross-reference the datasheet revision date to ensure compatibility with design requirements.

Selection Notes

Select this component when a fixed 3.8 V threshold is required for systems powered by voltages up to 5.5 V. Consider the 500 nA quiescent current for strict power budget constraints. Verify that the SC-70-3 package dimensions fit the PCB layout. Ensure the active low open-drain output configuration aligns with the downstream logic interface requirements.

Part Context

This part belongs to the MAX6348 series of ultra-low-power microprocessor reset circuits. The series offers various fixed thresholds and packages to monitor power supplies in portable electronics. The XR38 variant specifically denotes the SC-70-3 package with a 3.8 V threshold.
