Maxim Integrated MAX6375UR23+T Voltage Supervisor

The Maxim Integrated MAX6375UR23+T is a compact, highly precise voltage supervisor designed to monitor power supplies in digital systems. It ensures that the system microprocessor, FPGA, or other sensitive digital circuitry operates at optimal voltage levels. This voltage supervisor IC provides a reliable solution for systems that require a stringent power-on reset and power-fail warning.

This device features a factory-trimmed reset threshold voltage of 2.32V, which is ideal for 2.5V powered systems. It offers a low supply current of only 1.5µA, making it suitable for battery-operated and portable applications where power efficiency is crucial. The MAX6375UR23+T comes in a compact SOT-23 package, which is excellent for space-constrained applications.

One of the key features of the MAX6375UR23+T is its ability to provide a reset signal to the host system whenever the monitored voltage falls below the threshold. The reset output remains asserted for a minimum of 140ms after the voltage rises above the threshold, ensuring the system has enough time to stabilize before the reset is deasserted. This feature is critical for preventing system errors and data corruption that can occur if the system attempts to operate below its specified voltage range.

The device also includes a manual reset input, which allows an external signal to trigger a system reset. This can be useful for system maintenance or to recover from software errors. Additionally, the MAX6375UR23+T has an open-drain RESET output, which provides flexibility in interfacing with different logic levels and allows for wired-OR connections.

Designed with reliability in mind, the MAX6375UR23+T is capable of operating over a wide temperature range of -40°C to +125°C. This makes it suitable for industrial and automotive applications where temperature extremes are common.

In summary, the Maxim Integrated MAX6375UR23+T is a versatile and reliable voltage supervisor IC that offers precise monitoring, low power consumption, and a small footprint. Its robust feature set makes it suitable for a wide range of applications, including portable devices, embedded systems, and automotive electronics.
