Maxim Integrated MAX6375XR25-T Voltage Supervisor

The MAX6375XR25-T is a precision voltage supervisor designed by Maxim Integrated to monitor power supplies in microprocessor systems. It provides a significant layer of protection by ensuring that the system voltage remains within operational thresholds, thereby safeguarding the system from potential damage due to voltage fluctuations.

This compact device is housed in a small, 3-pin SC70 package, making it an ideal choice for space-constrained applications. The MAX6375XR25-T operates over a wide voltage range and features a fixed-sense threshold voltage of 2.5V, which is precisely preset by the manufacturer. This ensures consistent and reliable monitoring without the need for external components.

One of the key features of the MAX6375XR25-T is its low power consumption, which makes it suitable for battery-operated devices. It also boasts a low quiescent current of only 1.2µA at +25°C, further enhancing its efficiency in power-sensitive designs. The device has an operating temperature range of -40°C to +125°C, allowing it to perform reliably in a variety of environmental conditions.

The voltage supervisor offers a reset output that remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold. This delay ensures that the system has adequate time to stabilize before the processor starts up, thereby preventing any erroneous operation during power-up.

Additionally, the MAX6375XR25-T features an active-low RESET output, which provides a clear indication to the microprocessor when the monitored voltage falls below the acceptable range. This output can directly interface with the reset or interrupt line of a microprocessor, ensuring that the system responds quickly to a detected under-voltage condition.

Overall, the MAX6375XR25-T voltage supervisor from Maxim Integrated is a reliable and efficient solution for system protection. Its precision monitoring capabilities, combined with its low power consumption and small form factor, make it an excellent choice for a wide range of applications, including portable devices, embedded systems, and industrial equipment.
