Maxim Integrated MAX6315US26D1+ Low-Power Microprocessor Reset Circuit

The MAX6315US26D1+ is a highly reliable and compact microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system reliability through its ability to reset a µP during power-up, power-down, and brown-out conditions. With its small footprint and low power consumption, the MAX6315US26D1+ is an ideal solution for portable and space-constrained applications.

Key Features

• Precision Voltage Monitoring: This device features a factory-trimmed reset threshold voltage of 2.63V, ensuring accurate monitoring of the VCC supply voltage.
• Low Power Consumption: Designed for power-sensitive applications, it consumes a low quiescent current of only 1µA, making it suitable for battery-operated devices.
• Reset Signal: The MAX6315US26D1+ generates a reset signal when the VCC supply voltage falls below the reset threshold. The reset output remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold, ensuring a proper system reset.
• Manual Reset Input: A debounced manual reset input allows for a system reset to be initiated with an external pushbutton or logic signal.
• High Accuracy: The reset threshold accuracy is maintained over a wide temperature range of -40°C to +85°C, which guarantees reliable operation under varying environmental conditions.
• Immunity to Short VCC Transients: The device includes a built-in filtering capability to prevent false resets from short duration transients on the VCC line.

Applications

The MAX6315US26D1+ is designed for use in a variety of applications that require precise voltage monitoring and reliable reset functionality. It is commonly used in:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Data Storage
• Industrial Controllers
• Medical Devices

With its robust feature set and Maxim Integrated's reputation for quality, the MAX6315US26D1+ is an excellent choice for designers looking to enhance system stability and prolong operational lifespan of their digital systems.
