MAX6312EUK29D3+

Supervisors Overview

The MAX6312EUK29D3+T is a CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.5V to 5.0V and features a fixed reset threshold of 2.9V. The device monitors power supplies and asserts a system reset if any monitored supply falls outside the programmed threshold. It is housed in a compact SOT-23-5 package, suitable for portable applications.

Supervisors Feature Summary

• Monitors multiple power supplies and asserts reset when thresholds are exceeded
• Immune to short transients on monitored supply lines
• Guaranteed RESET valid down to VCC = 1V
• Low supply current consumption for portable designs

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable electronic devices requiring low power supervision
• Microprocessor system power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free certification prior to integration. Check for obsolescence notices as this series may have limited availability. Ensure packaging matches SOT-23-5 specifications for PCB compatibility.

Supervisors Selection Notes

Select this part when fixed threshold supervision at 2.9V is required without external programming components. Consider the SOT-23-5 footprint constraints and operating temperature range. Evaluate supply current requirements against other supervisory ICs if ultra-low power is critical. Verify input voltage ranges match system design parameters.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of multiple-input programmable reset ICs designed for monitoring complex power architectures. These devices offer factory-set thresholds in 100mV increments from 2.5V to 5.0V. The series is optimized for systems requiring reliable reset generation with minimal external component count.

Supervisors Replacement Considerations

Compatible substitutes include MAX6312 variants with different reset thresholds (e.g., MAX6312UK48D3+T for 4.8V threshold). Cross-reference pinout and package dimensions before substitution. Verify electrical characteristics such as supply current and reset timeout periods match application requirements.
