The MAX815TESA+T is an integrated circuit manufactured by Analog Devices for use in supervisory circuits, specifically designed for 3V and 5V microprocessors (uP). It offers accurate regulation with +/-1% accuracy, low power consumption in order to ensure utmost efficiency, and comprehensive solutions for power-on-reset (POR) and power-fail (PFI) events. The part also provides buffered outputs for resetting, holdoff, and power-fail detection. This part is designed for use in battery and general-purpose supervisory applications, offering a low-current threshold of 1.33V and a wide range of reset voltage adjustments. Its low power consumption also ensures long battery life and data retention for devices powered by a battery backup.
