Maxim Integrated MAX6467XS29D3+T Voltage Supervisor

The MAX6467XS29D3+T from Maxim Integrated is a high-quality voltage supervisor designed to provide precision monitoring of power supplies. This compact and efficient device is part of Maxim Integrated's extensive family of microprocessor (μP) supervisory circuits that cater to a wide range of applications. The MAX6467XS29D3+T is specifically tailored to ensure that digital systems operate reliably by monitoring their power supplies.

This voltage supervisor operates over a wide voltage range and is designed to maintain system integrity through various features. One of the key functions of the MAX6467XS29D3+T is its ability to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, ensuring that the system resets cleanly during power-up, power-down, and brownout conditions.

The reset output from the MAX6467XS29D3+T is guaranteed to be in the correct state for VCC down to 1V, making it suitable for low-voltage applications. Furthermore, it offers a factory-set reset threshold voltage of 2.93V, which is ideal for systems that operate at 3.3V power supply levels. The device's reset timeout period is also factory set at 280ms (min), providing a predictable delay for system recovery.

Designed with the needs of space-constrained applications in mind, the MAX6467XS29D3+T comes in a small, surface-mount SOT-343 package. This makes it an excellent choice for portable devices, where space is at a premium. Additionally, the supervisor is fully specified over the -40°C to +125°C extended temperature range, ensuring reliable operation in a variety of environments.

With its low supply current of only 1.2μA at 1.2V, the MAX6467XS29D3+T is energy efficient, which is particularly beneficial for battery-powered devices. The device also includes a manual reset input, allowing for an external trigger to initiate a system reset.

In summary, the MAX6467XS29D3+T voltage supervisor from Maxim Integrated is a robust, reliable, and versatile solution for monitoring power supplies in digital systems. Its combination of low power consumption, small package size, and precision voltage monitoring makes it an ideal choice for a broad range of applications.
