MAX6306UK29D3

Supervisors Overview

The MAX6306UK29D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range 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 timeout delay of 28ms. It monitors two inputs with a threshold voltage of 2.974V and consumes only 8µA of supply current. The component is housed in a compact SOT-23-5 package and supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Monitors multiple power supplies and asserts system reset if any monitored supply falls outside the programmed threshold
• Immune to fast transients on monitored supplies to prevent false triggering
• Includes a manual reset input for user-initiated system control

Supervisors Applications

• Portable computers
• Controllers
• Intelligent instruments
• Multivoltage systems (e.g., 3V/5V, 5V/12V)

Supervisors Procurement Notes

Verify availability status as this part may be subject to limited supply or discontinuation. Confirm RoHS compliance and lead time constraints directly with authorized distributors. Ensure the specific suffix matches required electrical parameters before ordering.

Supervisors Selection Notes

Select this component when monitoring dual voltage rails such as 5V and 3.3V in portable applications. The low quiescent current suits battery-powered designs. Verify that the factory-set threshold and timeout delay meet system requirements without external components.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin programmable reset ICs. These devices are optimized for personal computer systems and portable equipment requiring reliable power supervision in a small footprint.

Supervisors Replacement Considerations

Check MAX6306 variants with different suffixes for adjusted thresholds or delays. Cross-reference with MAX6305 or MAX6307 series for similar functionality with different pinouts or features.
