Maxim Integrated MAX6361LUT26 Microprocessor Reset Circuit

The MAX6361LUT26 from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant line of defense against power supply glitches and brownouts, ensuring that your system operates smoothly under variable and unpredictable power conditions. This compact, low-power component is an essential element for enhancing system reliability and robustness.

With its factory-trimmed reset threshold suitable for 2.63V power supplies, the MAX6361LUT26 ensures that your microprocessor will reset to a known state during power-up, power-down, or if the supply voltage drops below a predetermined level. The device maintains system integrity by providing a reset signal to the µP for a minimum of 140ms after VCC has risen above the reset threshold level. This precise timing ensures that the µP and other system components have sufficient time to stabilize before resuming operation.

The MAX6361LUT26 comes in a tiny, 6-pin SOT23 package, making it ideal for space-constrained applications. Despite its small size, it does not compromise on performance, offering low supply current specifications, typically 1.6µA at +25°C, which contributes to the overall power efficiency of the system it is implemented in.

Key features of the MAX6361LUT26 include:

• Presets reset threshold voltage suitable for 2.63V power supplies
• Guaranteed reset valid to VCC = 1V
• 140ms (min) reset pulse width
• Low supply current of 1.6µA (typ)
• Immune to short VCC transients
• Available in a 6-pin SOT23 package

This reset circuit is designed for a wide variety of applications, including computers, controllers, intelligent instruments, critical µP and µC power monitoring, and portable/battery-powered equipment. The MAX6361LUT26 is an excellent choice for designers looking for a combination of miniaturization, power-saving, and reliability in their system designs.

Maxim Integrated's commitment to high-quality and reliability ensures that the MAX6361LUT26 reset circuit is a trustworthy component for maintaining the integrity of your digital systems. By selecting this device, you can enhance the operational stability and safety of your products.
