Maxim Integrated MAX6381XR29D3+T Microprocessor Reset Circuit

The MAX6381XR29D3+T is a precision, low-power microprocessor (µP) reset circuit device from Maxim Integrated, designed to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required for managing power faults and ensuring stable system operation. This component is particularly suitable for applications that demand high accuracy and low power consumption, such as portable devices, computers, controllers, and intelligent instruments.

This reset circuit operates with a nominal threshold voltage of 2.93V, ensuring that the connected µP or digital system resets cleanly during power-up, power-down, or brown-out conditions. The MAX6381XR29D3+T features an active-low RESET output, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold level. This timeout period ensures that the system has sufficient time to stabilize before the processor begins operation.

The device comes in a compact, 3-pin SC70 package, making it an excellent choice for space-constrained applications. It is also characterized for operation over a wide temperature range of -40°C to +125°C, providing reliable performance in diverse environmental conditions.

One of the key benefits of the MAX6381XR29D3+T is its low supply current of just 1.2µA, which contributes to the energy efficiency of the overall system. This feature is particularly important for battery-powered devices where power conservation is crucial.

Additionally, the MAX6381XR29D3+T offers excellent transient immunity, ensuring that the device is not falsely triggered by fast transients on the V_CC line. This robustness against transients adds to the reliability of the system, preventing unnecessary resets that could lead to data loss or system downtime.

For manufacturers and designers looking to enhance the reliability of their digital systems with a high-quality reset circuit, the MAX6381XR29D3+T from Maxim Integrated is an ideal choice. Its precision voltage monitoring, low power consumption, and compact form factor make it a valuable component in any power-sensitive application.
