Product Overview: MAX6315US31D4+T by Maxim Integrated

The MAX6315US31D4+T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This precision device is engineered to maintain system integrity by monitoring the power supply voltage of digital systems. It is particularly well-suited for battery-powered applications due to its low power consumption and small footprint.

Key Features

• Voltage Monitoring: The MAX6315US31D4+T supervises a 3.1V power supply, ensuring that the system operates within acceptable voltage levels. It provides a reset signal to the microprocessor when the monitored voltage falls below the factory-set reset threshold, helping to prevent system errors and data corruption.
• Reset Timeout: Upon power-up, the device generates a reset pulse with a minimum duration of 140ms (typical) to ensure the system microprocessor starts in a known state.
• Low Power Consumption: With its ultra-low supply current of only 1µA (typical), the device is an excellent choice for portable and battery-operated equipment, where power efficiency is crucial.
• High Accuracy: The reset threshold accuracy is maintained at ±2% over temperature, which is critical for reliable system operation.
• Temperature Range: The device operates over a wide temperature range of -40°C to +85°C, making it suitable for use in a variety of environmental conditions.
• Package: It is offered in a compact SOT-143 package, which is ideal for space-constrained applications.
