Maxim Integrated MAX6334UR16D3-T Microprocessor Reset Circuit

The Maxim Integrated MAX6334UR16D3-T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant function in ensuring that the µP and its peripherals are reset properly during power-up, power-down, or brown-out conditions. This device is an essential component for systems that require a high level of reliability and precision.

Featuring a factory-trimmed reset threshold voltage of 1.6V, the MAX6334UR16D3-T is optimized for low-voltage applications. It is capable of holding the µP in reset for a minimum of 140ms (typical) after VCC has risen above the reset threshold level, ensuring that the system has sufficient time to stabilize before the processor starts executing code.

The compact SOT-23 package makes the MAX6334UR16D3-T an ideal choice for space-constrained applications. Its low supply current of 1µA (typical) makes it suitable for battery-powered and portable devices, where power efficiency is crucial.

Key features of the MAX6334UR16D3-T include:

• Factory-set reset threshold voltage: 1.6V
• Minimum reset timeout period: 140ms
• Low supply current: 1µA (typical)
• Guaranteed reset valid to VCC = 1V
• Power supply transient immunity
• No external components required
• Compact SOT-23 package

This device is designed to be highly immune to power supply transients, which is a critical feature for maintaining system stability. The MAX6334UR16D3-T does not require any external components, which simplifies the design and reduces the overall bill of materials for the system.

The MAX6334UR16D3-T is part of Maxim Integrated's family of µP supervisory circuits, which are known for their quality, reliability, and ease of use. It is an excellent choice for designers looking to enhance system reliability in microprocessor-based systems, including embedded controllers, intelligent instruments, and portable electronics.

Overall, the Maxim Integrated MAX6334UR16D3-T is a robust solution for system designers seeking to improve the operational stability and reliability of their digital systems.
