Maxim Integrated MAX6315US29D1 Low-Power Microprocessor Reset Circuit

The Maxim Integrated MAX6315US29D1 is a highly reliable and compact low-power microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with +2.5V to +5.0V powered circuits.

This device performs a single function: it 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 voltage threshold. The reset threshold for the MAX6315US29D1 model is precisely preset at the factory to 2.925V, making it ideal for applications with a 3.0V nominal supply voltage.

Key features of the MAX6315US29D1 include:

• Factory-Preset Reset Threshold: The reset threshold is accurately set at 2.925V, which is suitable for systems that operate at 3.0V.
• Low Power Consumption: This device is optimized for low-power operation, which helps extend the battery life of portable devices.
• Manual Reset Input: A manual reset input is provided to enable a microprocessor to initiate a reset independently.
• Immune to Short VCC Transients: Fast transients on the VCC line are filtered, ensuring stable operation without false resets.
• Compact SOT-143 Package: The small footprint of the SOT-143 package makes it suitable for space-constrained applications.

The MAX6315US29D1 is designed for use in a wide range of applications including computers, controllers, intelligent instruments, portable/battery-powered equipment, and embedded systems. Its robust design ensures that the digital system it is protecting is safeguarded against power supply glitches, brownouts, and other anomalies that could lead to system instability or data loss.

With Maxim Integrated's commitment to quality and reliability, the MAX6315US29D1 microprocessor reset circuit is a trusted solution for maintaining the integrity of your digital systems.
