Maxim Integrated Product: MAX6361PUT46+T

The MAX6361PUT46+T is a sophisticated, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications. This component is ideal for portable and space-constrained applications due to its small SOT23 packaging.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6361PUT46+T asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The reset threshold for this specific model is 4.63V, tailored for systems that operate at 5V power supply levels.

The device features a low supply current of 1.2µA (typical) at VCC = 3.3V, which is highly beneficial for battery-powered equipment. Its wide supply voltage range of 1.2V to 5.5V allows for versatile applications in various electronic systems. The MAX6361PUT46+T also has the capability to assert a reset signal upon manual activation through a debounce pushbutton input, which is a valuable feature for systems that require manual resets.

One of the key advantages of the MAX6361PUT46+T is its immunity to short VCC transients, which makes it a robust choice for unpredictable environments. It is offered in a 6-pin SOT23 package, which is lead(Pb)-free and RoHS compliant, making it an environmentally friendly option for modern electronics.

In summary, the MAX6361PUT46+T from Maxim Integrated is a highly reliable and efficient supervisory circuit that offers an array of features such as low power consumption, manual reset capability, and a wide operating voltage range, all in a compact package. It is an excellent choice for system designers looking to enhance the reliability and performance of their microprocessor-based systems.
