Maxim Integrated MAX6467US29D3+T Voltage Supervisor

The MAX6467US29D3+T from Maxim Integrated is a highly reliable and compact voltage supervisor designed to ensure the stability and proper operation of your electronic systems. This microprocessor (μP) supervisory circuit is engineered to monitor the power supplies in μP and digital systems, providing a significant layer of protection against low voltage, which can lead to system errors and instability.

This particular model, the MAX6467US29D3+T, offers a preset threshold voltage of 2.93V, which is ideal for systems that operate around the common 3.3V supply level. Upon detecting a voltage that falls below this threshold, the device asserts a reset signal to the system, which remains asserted for a minimum of 140ms after the supply voltage exceeds the reset threshold. This ensures that the system has ample time to stabilize before normal operation resumes.

The MAX6467US29D3+T comes in a compact SOT-143 package, making it suitable for space-constrained applications. It is also characterized by its low power consumption, which helps to minimize the overall power drain on the system, thereby enhancing energy efficiency and prolonging battery life in portable applications.

Key features of the MAX6467US29D3+T include:

• A precise factory-set reset threshold voltage of 2.93V
• Low supply current of 5.5μA (typical) at VDD = 3.6V, which is ideal for battery-powered equipment
• Immunity to short VDD transients, ensuring reliable operation even in noisy environments
• An active-low, push-pull RESET output, which provides a direct interface to the reset or enable input of the target microprocessor without requiring external components
• Capability to operate over a wide temperature range of -40°C to +125°C, suitable for industrial applications

This voltage supervisor is also offered in tape and reel packaging, denoted by the "+T" suffix, making it suitable for automated assembly processes, and thus an excellent choice for high-volume production. With its robust design and essential protective functions, the MAX6467US29D3+T is a critical component for any design that requires a reliable power-on reset functionality.

Whether you're designing consumer electronics, portable devices, or complex industrial systems, the Maxim Integrated MAX6467US29D3+T voltage supervisor provides the necessary protection to ensure your application runs smoothly and reliably.
