Maxim Integrated's MAX6746KA26: A Robust Voltage Monitoring Solution

The MAX6746KA26 from Maxim Integrated is a highly reliable and precise microprocessor (µP) supervisory circuit designed to maintain system integrity by monitoring the power supply voltage. This compact device is specifically engineered to prevent system errors and data corruption during power failures or brown-out conditions.

Featuring a fixed factory-set reset threshold of 2.63V, the MAX6746KA26 ensures that your system operates within safe voltage levels. It is the perfect solution for portable devices, microcontrollers, and other digital systems that require a stable and reliable power supply for optimal performance.

The MAX6746KA26 boasts a low supply current of only 5.5µA, making it an energy-efficient choice for battery-powered applications where power conservation is crucial. This device operates over a wide voltage range of 1.2V to 5.5V, providing versatility for different system designs and power requirements.

One of the key features of the MAX6746KA26 is its ability to provide a reset signal to the host microprocessor during power-up, power-down, and brown-out conditions. This reset signal is maintained for a minimum of 140ms after the supply voltage exceeds the reset threshold, ensuring that the µP has sufficient time to return to a stable state before resuming operation.

In addition to its core functionality, this supervisory circuit offers a manual reset input, enabling system designers to trigger a reset manually when needed. The device also includes a debounced manual reset input, which further enhances system reliability by filtering out any noise or glitches that could inadvertently cause a reset.

The MAX6746KA26 comes in a compact SOT-23 package, which is ideal for space-constrained applications. Its small footprint and low profile make it an excellent choice for portable electronics, where size and weight are critical considerations.

With its combination of precise voltage monitoring, low power consumption, and compact design, the MAX6746KA26 from Maxim Integrated is an indispensable component for ensuring the stability and reliability of your electronic systems.
