The MAX6345MUT-T from Maxim Integrated is a high-quality microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a single 3.3V power supply rail.

This robust component ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6345MUT-T asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. This feature ensures that the system has sufficient time to stabilize during power-up.

Key Features:

• Precision Monitoring: The device includes a precision voltage monitor that keeps a close eye on the 3.3V power supply.
• Power-On Reset Delay: It features a 140ms min power-on reset delay which ensures proper system reset on power-up.
• Manual Reset Input: A manual reset input is provided, allowing the flexibility to initiate a system reset from an external source.
• Low Power Consumption: With its low supply current of 20µA (typical), it contributes to the overall power efficiency of the system.
• Compact SOT23 Package: The component is available in a small 6-pin SOT23 package, making it suitable for space-constrained applications.
• Temperature Range: It operates over an extended temperature range of -40°C to +85°C, accommodating a wide range of environmental conditions.

Designed to increase system reliability, the MAX6345MUT-T is an ideal solution for portable/PDA, networking, computers, controllers, and embedded systems. Its ease of integration, combined with Maxim Integrated's reputation for high-quality components, makes it a top choice for engineers and designers looking to enhance system stability and performance.
