MAX6307UK46D3+T

Supervisors Overview

The MAX6307UK46D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a SOT-23-5 package and supports two monitored inputs with thresholds of 3.3V and 5V. The device provides an active low, open-drain reset output with a manual reset input capability. Key electrical parameters include a maximum supply voltage of 5.5V, a typical operating current of 8µA, and a reset delay time of 200ms. It operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors multiple power supplies simultaneously for system integrity
• Immune to short transients on monitored supply lines
• Includes manual reset input for user-initiated system resets
• Operates with low supply current suitable for portable applications

Supervisors Applications

• Portable computers and handheld devices
• Personal computer systems monitoring 5V and 3.3V rails
• Controllers and intelligent instruments
• Multivoltage embedded control systems

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status in some regions. Confirm RoHS compliance details and lead-free specifications match project requirements. Check datasheet revision history for any updates to electrical characteristics or pinout configurations before finalizing design integration.

Supervisors Selection Notes

Select this part when simultaneous monitoring of two distinct voltage levels is required. Ensure the 200ms reset timeout aligns with system startup timing constraints. Verify that the open-drain output interface is compatible with the target processor's reset input logic levels and pull-up requirements.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. Designed specifically for personal computer systems to monitor both 5V and 3.3V supplies. The series offers factory-set thresholds in 0.1V increments from 2.5V to 5V, ensuring precise supervision without external components.

Supervisors Replacement Considerations

Consider MAX6307EUK46D3+T for similar functionality with potential lead-free variations. MAX6309EUK46D3+T offers comparable multi-input supervision with manual reset features. Verify package compatibility and threshold voltage accuracy when substituting within the MAX630x series.
