Maxim Integrated MAX16081XR29F+T Supervisory Circuit

The MAX16081XR29F+T from Maxim Integrated is a compact, highly precise supervisory circuit designed to monitor single-system supply voltages. This device is an essential component for systems that require a high level of reliability and accuracy in voltage monitoring to ensure proper operation and protection.

Featuring a factory-trimmed reset threshold of 2.925V, the MAX16081XR29F+T is ideal for managing power supplies in a range of electronic applications. With its low supply current of only 1.5µA, this supervisory circuit is especially suitable for battery-operated devices where power efficiency is crucial.

The supervisory circuit provides a reset output during power-up, power-down, and brownout conditions. Once the monitored supply voltage falls below the reset threshold, the reset signal is asserted and held for a minimum reset timeout period after the supply voltage rises above the reset threshold, ensuring a proper system reset. The reset timeout period is internally set, which eliminates the need for external components and simplifies the design process.

The MAX16081XR29F+T comes in a tiny, 4-pin SC70 package, making it an excellent choice for space-constrained applications. Its operating temperature range of -40°C to +125°C allows for deployment in environments with varying temperature conditions, maintaining performance across a broad spectrum of industrial and commercial applications.

Key features of the MAX16081XR29F+T include:

• Factory-Trimmed V_CC Reset Threshold
• Low 1.5µA Supply Current
• Immune to Short V_CC Transients
• Guaranteed Reset Valid to V_CC = 1.0V
• Internally Set Reset Timeout Period
• Compact 4-Pin SC70 Package
• Wide Operating Temperature Range: -40°C to +125°C

The MAX16081XR29F+T supervisory circuit is available in tape and reel format, denoted by the suffix 'T', which facilitates automated assembly processes for high-volume production. Maxim Integrated's commitment to quality and reliability makes this supervisory circuit a trusted choice for critical system monitoring tasks.
