Maxim Integrated MAX6420UK29+T Voltage Detector

The MAX6420UK29+T from Maxim Integrated is a highly precise, low-power voltage detector designed for a variety of applications that require voltage monitoring and battery management. This compact and efficient component is a crucial element for systems that need to maintain stable operation even under fluctuating power conditions.

The device is characterized by its small SOT23 package, making it suitable for space-constrained applications. Its tiny footprint allows for easy integration into modern PCB designs, without sacrificing performance or reliability. With its factory-trimmed threshold voltage of 2.925V, the MAX6420UK29+T ensures accurate monitoring for 2.9V-powered circuits.

One of the key features of this voltage detector is its low quiescent current, which is typically 1.2µA at +25°C. This makes it an ideal choice for battery-powered devices where power conservation is critical. The low power consumption extends the life of the battery, ensuring that devices remain operational for longer periods without requiring frequent battery replacements.

The MAX6420UK29+T offers a ±1.5% threshold accuracy over the entire operating temperature range of -40°C to +125°C. This high level of precision guarantees reliable voltage detection, which is essential for protecting sensitive electronic components from under-voltage conditions. Furthermore, the device provides a 140ms (min) reset timeout period, which allows the system to stabilize before resuming normal operation after a voltage fault is detected.

With its open-drain output, the MAX6420UK29+T can interface easily with a variety of microcontrollers and other digital circuits. The open-drain configuration allows for the connection of the output to a voltage higher than VCC, providing greater flexibility in system design.

In summary, the Maxim Integrated MAX6420UK29+T voltage detector is a robust and reliable solution for systems requiring accurate voltage monitoring. Its compact size, low power consumption, and high precision make it an excellent choice for portable devices, consumer electronics, and industrial applications where consistent performance and long-term reliability are paramount.
