Maxim Integrated MAX6713TEXS Microprocessor Supervisor

The Maxim Integrated MAX6713TEXS is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with 3.3V, 3V, and 2.5V powered circuits.

This supervisor IC ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6713TEXS features a manual reset input that allows the user to trigger a reset. This is an essential function for most microprocessor-based systems as it ensures that the processor starts in the same state each time it is powered up or in the event that manual intervention is required to reinitialize the system without cycling the power.

The device's reset timeout is factory-set to a precise value, eliminating the need for external timing components. The MAX6713TEXS has a reset timeout period of 140ms (min) which provides a sufficient delay to allow the power supply and the processor to stabilize before the system starts operating.

Additionally, the MAX6713TEXS features an active-low, open-drain reset output, which remains asserted for the reset timeout period after V_CC returns to an in-tolerance condition or after a manual reset input. This open-drain output allows for the connection of multiple supervisors to a common reset line, enabling a system-wide reset from several sources.

The device operates over a wide supply voltage range and consumes low supply current, making it suitable for battery-operated applications. The MAX6713TEXS is available in a compact 5-pin SOT-23 package, making it ideal for space-constrained applications without compromising on functionality.

In summary, the Maxim Integrated MAX6713TEXS microprocessor supervisor is a versatile and essential component for ensuring the reliability and correct operation of microprocessor systems, particularly during power-up, power-down, and voltage dips.
