Maxim Integrated MAX6858UK27D1+T Microprocessor Supervisory Circuits

The MAX6858UK27D1+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This compact device is an essential component for managing system resets and monitoring power supply voltages in microprocessor-based systems. The MAX6858UK27D1+T is part of Maxim's extensive line of supervisory circuits that are engineered to ensure that digital systems boot up correctly every time.

This supervisory IC operates over a wide voltage range and offers a fixed reset threshold voltage of 2.7V, making it suitable for 3V-powered systems. The device is housed in a small SOT-23 package, which is ideal for space-constrained applications. Its small footprint allows designers to save valuable board space while maintaining robust power management capabilities.

One of the key features of the MAX6858UK27D1+T is its ability to assert a reset signal whenever the VCC supply voltage falls below the reset threshold. The reset output remains asserted for a preset timeout period after VCC rises above the reset threshold, ensuring that the system has adequate time to stabilize before resuming operation. This feature helps prevent system errors and data corruption during power-up, power-down, and brownout conditions.

The device also offers a manual reset input, which provides a hardware-driven reset signal. This allows for an external signal or switch to initiate a system reset, providing an additional layer of control for system maintenance or emergency situations.

With its low supply current, the MAX6858UK27D1+T is also optimized for low-power applications, making it an excellent choice for battery-operated devices. Its wide operating temperature range ensures reliable performance across various environmental conditions, from industrial to consumer applications.

In summary, the MAX6858UK27D1+T from Maxim Integrated offers a robust set of features for microprocessor system supervision, including a fixed reset threshold, manual reset capability, low power consumption, and a compact form factor. It's an ideal solution for designers looking to enhance the reliability and performance of their digital systems.
