Maxim Integrated MAX6385XS16D3-T Microprocessor Reset Circuit

The Maxim Integrated MAX6385XS16D3-T is a compact, high-precision 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 1.6V power supply voltage.

This reset circuit is specifically engineered to maintain system integrity by monitoring the power supply voltage. It asserts a reset signal whenever the VCC supply voltage falls below its preset threshold, ensuring that the microprocessor, microcontroller, or other digital logic starts up in a known state. The reset signal remains asserted for a minimum timeout period after VCC has risen above the reset threshold, providing the system adequate time to stabilize.

The MAX6385XS16D3-T features a factory-set reset threshold voltage, tailored for applications that operate at 1.6 volts. Its reset timeout period is also factory-set, eliminating the need for external timing components. This device is available in a small, space-saving 4-pin SC70 package, making it ideal for portable and space-constrained applications.

Key features of the MAX6385XS16D3-T include:

• Factory-Set Reset Threshold Voltage for 1.6V Systems
• Factory-Set Reset Timeout Period
• Low Supply Current, Ideal for Battery-Powered Equipment
• Guaranteed Reset Valid to VCC = 1.0V
• Immune to Short VCC Transients
• Push-Pull RESET Output
• Compact 4-Pin SC70 Package

This microprocessor reset circuit is particularly well-suited for use in portable devices, such as PDAs, mobile phones, and portable media players. Its push-pull RESET output ensures compatibility with a wide range of microprocessors and digital systems. The MAX6385XS16D3-T's low supply current feature contributes to extended battery life, making it a smart choice for power-sensitive applications.

Overall, the Maxim Integrated MAX6385XS16D3-T provides a reliable and cost-effective solution for system monitoring and power management, ensuring that digital systems operate smoothly and efficiently.
