MAX6348XR35-T

Overview

The MAX6348XR35-T is a single-channel 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 an active low, open drain output type. The device monitors one input with a threshold voltage of 3.5 V and provides a reset delay time of 260 ms. It functions in temperatures from -40°C to +85°C, consumes 500 nA of working power current, and has an accuracy of 1.5%. The component is housed in an SC-70-3 package.

Feature Summary

• Ultra-low-power operation with minimal supply current consumption for battery-sensitive applications
• Compact surface-mount packaging suitable for space-constrained designs
• Active low open-drain output configuration for flexible interfacing

Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Consumer electronics power management

Procurement Notes

Verify the exact suffix against official documentation, as standard listings often use '+T'. Confirm availability status directly with authorized distributors due to potential supply restrictions. Ensure the specific threshold voltage variant matches the design requirements before ordering.

Selection Notes

Select this component when a fixed 3.5 V threshold is required for single-voltage monitoring. Consider the 260 ms reset delay and 500 nA current draw relative to system power budgets. Verify compatibility with the SC-70-3 footprint and operating temperature range.

Part Context

Part of the MAX6348 series of ultra-low-power reset circuits designed for microprocessor systems. The series offers various threshold voltages and packages to accommodate different voltage monitoring needs while maintaining low power consumption.

Replacement Considerations

Check for direct substitutes within the MAX6348 family with matching thresholds or consider the MAX6348UR35+T if SOT-23-3 packaging is acceptable.
