Maxim Integrated MAX6746KA29+T Voltage Supervisory IC

The MAX6746KA29+T from Maxim Integrated is a compact, low-power voltage supervisory IC designed to monitor power supplies in digital systems and provide a reset signal to microcontrollers (MCUs) and microprocessors (MPUs) whenever the monitored power supply falls below a predefined threshold. This tiny, efficient component is essential for ensuring reliable operation of digital electronics by providing system initialization on power-up, power-down, and brown-out conditions.

Key Features

• Voltage Threshold Precision: The device comes with a factory-set reset threshold voltage of 2.925V, suitable for 3V-powered systems, ensuring accurate monitoring without the need for external resistors.
• Low Power Consumption: With a quiescent current of just 5.5µA, the MAX6746KA29+T is ideal for battery-operated and portable devices where power efficiency is crucial.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be triggered by external hardware or software controls, offering additional system management flexibility.
• Reset Timeout: The reset output remains asserted for a minimum timeout period after the monitored voltage exceeds the threshold, ensuring system stability during transient conditions.
• Operating Temperature Range: The device is designed to operate over the extended industrial temperature range, from -40°C to +125°C, making it suitable for harsh environments.
