Analog Devices Inc.'s MAX6314US30D1 - Microprocessor Reset Circuit

The MAX6314US30D1 is a compact, high-precision microprocessor (µP) supervisory circuit designed by Analog Devices Inc. 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 3V power supply.

This supervisory circuit ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6314 comes with a factory-trimmed reset threshold voltage of 3.0V, making it suitable for operation with standard 3V power supplies and battery-operated equipment.

One of the key features of the MAX6314US30D1 is its ability to provide a precise reset output without any external components. The reset output remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold level, ensuring that the µP has adequate time to stabilize and that the reset has been de-asserted properly.

The device is highly integrated, featuring a debounced manual reset input which allows a reset to be asserted manually with a push-button or other input signal. Additionally, the MAX6314 has a low supply current of 1.5µA (typical), which is vital for power-sensitive applications.

The MAX6314US30D1 is available in a small 4-pin SOT-143 package, making it ideal for space-constrained applications. Its temperature range of -40°C to +85°C allows it to operate reliably in a broad range of environments and applications.

With its combination of features, the MAX6314US30D1 is an excellent choice for use in portable devices, computers, controllers, and other digital systems that require a reliable reset function. Designers can trust this device from Analog Devices Inc. to maintain system integrity and ensure proper operation through all conditions.

Overall, the MAX6314US30D1 is a testament to Analog Devices Inc.'s commitment to providing high-quality, reliable integrated circuits that enhance the performance and stability of electronic systems.
