MAX6306EUK29D3+T

Supervisors Overview

The MAX6306EUK29D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of up to 5.5V and features an active low, open-drain reset output. The device includes a manual reset input and provides a fixed reset threshold of 2.9V with a typical reset delay time of 1.4ms. It draws a maximum operating supply current of 8µA and functions reliably across temperatures from -40°C to +85°C. Packaged in a compact SOT-23-5 format, it supports under/overvoltage monitoring without external components.

Supervisors Feature Summary

• Monitors multiple power supply inputs to assert system reset when voltages fall outside programmed thresholds
• Features immunity to fast transients on monitored supplies to prevent false triggering
• Includes a manual reset input for user-initiated system control
• Operates with ultra-low supply current suitable for portable and battery-powered applications

Supervisors Applications

• Portable computers and handheld devices
• Personal computer systems monitoring 5V and 3.3V rails
• Battery-powered equipment requiring voltage supervision
• Multivoltage systems such as 3V/5V or 5V/12V configurations

Supervisors Procurement Notes

Verify the complete part number including suffixes against official Analog Devices documentation to ensure correct threshold voltage and package variant. Confirm RoHS compliance status and lead-free specifications prior to integration. Check current availability and lifecycle status as distribution may vary by region. Ensure compatibility with existing PCB footprint and thermal requirements during procurement planning.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required in space-constrained designs. The fixed 2.9V threshold suits specific logic level supervision needs. Consider the 8µA quiescent current for battery life optimization. Verify that the open-drain output configuration aligns with the target system's reset input requirements and pull-up resistor capabilities.

Supervisors Part Context

This device belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These circuits are engineered for microprocessor supervision in environments requiring reliable power management. The family shares common architectural features including transient immunity and low power consumption, differentiated primarily by factory-set threshold voltages and timeout delays.

Supervisors Replacement Considerations

Cross-reference with other MAX6306 variants having identical SOT-23-5 packaging and similar threshold characteristics. Verify functional equivalence regarding reset delay times and output drive capabilities before substitution.
