The MAX6315US29D4+T is a precision, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required for modern electronic applications. This supervisory circuit ensures that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

Key Features

• Voltage Monitoring: The device monitors a preset threshold voltage of 2.93V, making it suitable for 3.3V powered circuits.
• Reset Output: It offers a reset output which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level. This ensures the system microprocessor starts up correctly every time.
• Low Power Consumption: With its low supply current of 1µA (typical), the MAX6315US29D4+T is ideal for power-sensitive applications.
• High Accuracy: The reset threshold accuracy is ±2%, providing a reliable reset operation without false triggering.
• Temperature Range: The device operates over an industrial temperature range of -40°C to +85°C, suitable for most environmental conditions.
• Form Factor: It comes in a compact SOT-143 package, saving space on the PCB.
