MAX6309UK29D3

Supervisors Overview

The MAX6309UK29D3 is a 5-pin, multiple-input programmable reset integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors up to two power supply inputs and provides an active-low push-pull reset output. The device features a manual reset input for user-initiated system resets. Key electrical parameters include a maximum supply voltage of 5.5 V, a typical operating current of 8 uA, and a reset delay time of 1.4 ms. The threshold voltage is fixed at 2.925 V with an accuracy of 2.5%. It operates within a temperature range of -40°C to +85°C and is housed in a SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Supports monitoring of multiple power supply inputs simultaneously
• Features a manual reset input for direct control
• Provides an active-low push-pull reset output signal

Supervisors Applications

• Personal computer systems requiring dual voltage supervision
• Embedded systems monitoring 5V and 3.3V rails
• Industrial control units with multiple power domains

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free designation based on specific lot codes. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure packaging specifications match design requirements for surface mount assembly processes.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required within a single package. Consider the 8 uA quiescent current for low-power applications. Verify that the 1.4 ms reset delay aligns with system startup timing requirements. Ensure the SOT-23-5 footprint fits the PCB layout constraints.

Supervisors Part Context

The MAX6309 belongs to the MAX6305–MAX6313 family of CMOS microprocessor supervisory circuits designed for multi-supervision tasks. These devices are optimized for applications needing reliable reset generation across varying power conditions.
