MAX6384XS31D3+T

Supervisors Overview

The MAX6384XS31D3+T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8V to 5.5V and features a fixed reset threshold voltage of 3.08V. The device provides an active-low, push-pull reset output with a manual reset input capability. It consumes low power, drawing only 7µA at 1.8V. The component supports a reset delay time of 2ms and functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a compact SC-70-4 surface-mount package.

Supervisors Feature Summary

• Monitors power-supply voltages from 1.8V to 5.0V while maintaining ultra-low supply current consumption.
• Features a debounced manual reset input with an internal pullup resistor for user-initiated system resets.
• Provides a push-pull active-low reset output that asserts when the monitored voltage falls below the factory-set threshold.

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Handheld instruments and medical devices
• Wireless communications systems
• Personal digital assistants (PDAs) and mobile phones

Supervisors Procurement Notes

Verify the exact suffix D3 against the manufacturer's official datasheet to confirm the specific reset timeout value and pin configuration. Ensure the ordering part number matches the required lead-free status and packaging type. Cross-reference the threshold voltage specifications with the design requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervision with a manual reset function is required. The push-pull output drives loads directly without external resistors. Consider the SC-70-4 package size for space-constrained designs. Verify that the 3.08V threshold aligns with the target supply rail stability requirements.

Supervisors Part Context

This part belongs to the MAX6381–MAX6390 family of µP reset circuits. These devices are designed to monitor power-supply voltages and provide reset signals to microprocessors and memory devices. The family offers various output types, timeout delays, and monitoring channels to suit different system architectures.

Supervisors FAQ

Does the MAX6384XS31D3+T include a watchdog timer?

No, this specific model does not feature a watchdog timer; it is a basic voltage supervisor with manual reset capability.

What is the output type of the reset signal?

The reset output is active-low and push-pull, allowing it to source and sink current directly.
