Maxim Integrated MAX802TESA+T Voltage Supervisor IC

The MAX802TESA+T from Maxim Integrated is a precision voltage supervisor IC designed to maintain system integrity by monitoring the power supply voltage in digital systems. This compact, highly reliable component is an essential part of any system where data integrity is critical, and power fluctuations need to be managed effectively.

Encased in an 8-pin SOIC package, the MAX802TESA+T is engineered to detect under-voltage conditions, thereby safeguarding microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive devices from unpredictable system behavior that can arise during power-up, power-down, or if the supply voltage drops unexpectedly during normal operation. When the monitored voltage falls below the factory-set reset threshold, the reset output is asserted, which remains active until the voltage recovers and a reset timeout period has elapsed, ensuring the system has stabilized before operation resumes.

The device features a reset threshold voltage of 4.65V, which is suitable for 5V-powered systems. Its active-low reset output is guaranteed to be in the correct state for VCC down to 1V, which provides a wide operating range. The MAX802TESA+T also boasts a low supply current of only 40µA (typical), making it an energy-efficient choice for power-sensitive applications.

Furthermore, the MAX802TESA+T offers an impressive temperature range from -40°C to +85°C, which allows it to perform reliably in a variety of environmental conditions. This makes it an ideal voltage monitoring solution for industrial, automotive, and consumer electronics where temperature extremes are common.

Maxim Integrated's commitment to quality and reliability is evident in the design and production of the MAX802TESA+T. With its precise voltage monitoring capabilities and robust feature set, this voltage supervisor IC is an excellent choice for designers who require a high level of system stability and protection against power supply anomalies.

Incorporating the MAX802TESA+T into your design will ensure that your systems operate reliably and continue to provide the performance expected, even in the face of challenging power conditions.
