MAX6315US30D1+TG05

Supervisors Overview

The MAX6315US30D1+T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 3 V. The device provides an active low, open-drain output with a reset delay time of 1.4 ms. It supports manual reset functionality and lacks watchdog or battery backup switching capabilities. Operating temperatures span from -40°C to +125°C with an accuracy of 1.8%. The part consumes 5 µA of operating supply current and dissipates up to 320 mW. It is housed in a SOT-143-4 package.

Supervisors Feature Summary

• Provides system reliability by monitoring power supplies and asserting a reset signal when voltage falls below the preset threshold.
• Features a debounced manual reset input for user-initiated system resets.
• Offers bidirectional compatibility and direct connection capability for microprocessor systems.

Supervisors Applications

• Microprocessor (µP) and digital system power supply monitoring
• Battery-powered portable applications requiring low supply current
• Systems requiring manual reset functionality

Supervisors Procurement Notes

Verify the specific suffix 'TG05' against official manufacturer documentation, as standard datasheets typically list 'MAX6315US30D1+T'. Confirm RoHS compliance status and lead-free designation directly with the supplier. Ensure the SOT-143-4 package dimensions match your PCB footprint requirements. Validate that the 3 V threshold aligns with your target supply voltage specifications before procurement.

Supervisors Selection Notes

Select this component for applications requiring a single-input voltage supervisor with manual reset capability. The low 5 µA supply current makes it suitable for battery-operated devices. The wide operating temperature range (-40°C to +125°C) ensures robustness in harsh environments. Choose this part over variants with watchdog timers if manual intervention is preferred for system recovery.

Supervisors Part Context

The MAX6315 belongs to the Maxim Integrated MAX631x series of microprocessor supervisory circuits. This family is designed to monitor power supplies in µP and digital systems, eliminating external components. The MAX6315 specifically offers an open-drain output and manual reset input, distinguishing it from push-pull or watchdog-enabled variants within the same product line.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the MAX631x family. Verify pinout compatibility and electrical parameters such as threshold voltage and reset delay time. Ensure any replacement maintains the required manual reset functionality and open-drain output configuration.
