Maxim Integrated MAX6834GXRD0+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6834GXRD0+T is a highly compact and efficient microprocessor supervisory circuit designed to monitor power supplies in microprocessor systems. It provides a significant level of protection to ensure that the system operates reliably and without interruption. This supervisory circuit is an essential component for applications that require precise voltage monitoring and power management.

One of the key features of the MAX6834GXRD0+T is its ability to assert a reset signal whenever the VCC supply voltage falls below a preset threshold. This reset signal is maintained for a minimum of 140ms after VCC has risen above the reset threshold, ensuring that the microprocessor has adequate time to initialize and stabilize before commencing operations. This feature is particularly useful for systems that are sensitive to power fluctuations and need to maintain data integrity during power-up or brownout conditions.

The device offers a low supply current, typically 1.5µA, which makes it suitable for battery-operated equipment where power conservation is critical. The MAX6834GXRD0+T operates over a wide voltage range of 1.2V to 5.5V, accommodating various microprocessor and logic supply voltages, thereby providing design flexibility for different system requirements.

Furthermore, the MAX6834GXRD0+T comes in a tiny, surface-mount SOT-23 package, which is ideal for space-constrained applications. Its small footprint allows it to be easily integrated into compact system designs without compromising on performance.

This supervisory circuit is also characterized by its robustness, with the ability to operate over the extended temperature range of -40°C to +125°C, making it suitable for industrial and automotive environments where temperature extremes are common.

In summary, the Maxim Integrated MAX6834GXRD0+T is a versatile and reliable solution for system voltage monitoring and power management. Its low power consumption, wide operating voltage range, compact packaging, and extended temperature range make it an excellent choice for a broad spectrum of applications, from portable devices to automotive and industrial systems.
