Maxim Integrated MAX6315US26D3+T Low-Power, Quad Voltage µP Reset Circuit

The MAX6315US26D3+T is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. Manufactured by Maxim Integrated, this device is essential for systems that require precision voltage monitoring and a robust reset feature. It ensures that the µP and its peripherals are reset properly during power-up, power-down, or brown-out conditions.

Featuring a factory-trimmed reset threshold voltage of 2.63V, the MAX6315US26D3+T provides a precise monitoring solution for 2.6V-powered circuits. With its low supply current draw of only 1µA, this device is an excellent choice for battery-powered applications where power conservation is crucial.

The MAX6315US26D3+T comes in a compact SOT-143 package, making it suitable for space-constrained applications. It offers a robust set of features, including a quad voltage monitor, which allows the device to monitor multiple supply voltages simultaneously, ensuring that all system voltages remain within specified limits.

One of the key features of this supervisory circuit is its active-low reset output. The reset signal is asserted when any of the monitored voltages fall below the factory-set thresholds, and it remains asserted for a minimum reset timeout period after all voltages have risen above the reset thresholds. This ensures a proper system reset and gives the system time to stabilize before resuming operation.

Additionally, the MAX6315US26D3+T is designed for high-reliability applications. It includes an immunity to short voltage transients and an ability to reject fast transients on the monitored voltage rails. This makes the device particularly well-suited for industrial, automotive, and other environments where electrical noise and sudden voltage changes can be problematic.

For designers and engineers looking for a reliable solution to protect their digital systems from improper operation due to voltage fluctuations, the MAX6315US26D3+T from Maxim Integrated offers a high-quality, easy-to-implement solution that combines low power consumption with high precision and robust protection features.
