MAX6468XS22D3-T

Overview

The MAX6468XS22D3-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors single power-supply voltages ranging from +1.8V to +5.0V and asserts a reset signal if the supply voltage drops below its preset threshold of 2.188V. The device features an active-low, push-pull output with a minimum reset timeout of 150ms. It operates within a temperature range of -40°C to +125°C and consumes a typical quiescent current of 7µA. The component is housed in a compact SC-70 package.

Feature Summary

• Integrates an edge-triggered, one-shot manual reset function that ensures the microprocessor enters reset mode for a fixed timeout period only, even during continuously asserted manual reset conditions.

Applications

• Microprocessor system supervision
• Single power-supply voltage monitoring
• Embedded controller reset generation

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as '+T' variants typically denote lead-free construction, but cross-reference with the manufacturer's latest documentation to ensure alignment with environmental regulations. Check availability status as some distributors may list this part as discontinued or limited stock.

Selection Notes

Select this component when a fixed 2.188V threshold is required for systems operating between 1.8V and 5.0V. Choose the SC-70 package for space-constrained designs. Ensure the 150ms minimum reset timeout aligns with the target microprocessor's startup requirements. Verify that the active-low push-pull output interface matches the system's input logic levels.

Part Context

The MAX6468XS22D3-T belongs to the MAX6467/MAX6468 family of microprocessor supervisory circuits. This series provides reliable reset generation for embedded systems by monitoring power supply integrity. The 'XS' designation typically refers to specific threshold voltage options within the broader product line, offering factory-trimmed accuracy without external components.

FAQ

How does the manual reset function behave during continuous activation?

The edge-triggered, one-shot manual reset function ensures the microprocessor enters the reset mode for a fixed timeout period only, preventing indefinite reset states even if the manual reset signal remains asserted.

What is the reset timeout duration for this specific model?

The MAX6468XS22D3-T has a minimum reset timeout of 150ms, which accommodates various microprocessor platforms requiring faster recovery times compared to the 1200ms option available in other variants.
