Product Overview: MAX6381XR26D3+T

The MAX6381XR26D3+T is a highly precise, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 2.6V power supply voltage.

Key Features

• Voltage Monitoring: This device keeps a watchful eye on the system voltage, ensuring it remains within operational limits, with a factory preset threshold of 2.6V.
• Reset Output: Upon detection of an out-of-tolerance power supply condition, the MAX6381XR26D3+T asserts a reset signal to the host microprocessor, holding it in reset for a minimum of 140ms after the power supply has returned to an in-tolerance condition.
• Low Power Consumption: Designed for power-sensitive applications, this device consumes minimal power, making it ideal for battery-operated systems.
• Push-Pull Active-Low Reset Output: The output type is push-pull with an active-low reset output, which provides a direct interface to the reset or enable input of the microprocessor, without the need for external transistors or pull-up resistors.
• Temperature Range: It operates over the extended -40°C to +125°C temperature range, making it suitable for use in a variety of environments.
• Package: The MAX6381XR26D3+T is offered in a compact, 3-pin SC70 package, which is designed to save board space in space-constrained applications.

Applications

With its precision voltage monitoring and low-power operations, the MAX6381XR26D3+T is well-suited for a wide range of applications, including:

• Portable/Battery-Powered Equipment
