Introducing the MAX6314US26D2-T from Maxim Integrated

The MAX6314US26D2-T is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant line of defense against system failures caused by erratic power supplies or unexpected power-down events. This component is an essential element for any design where data integrity and system uptime are of paramount importance.

With its factory-trimmed reset threshold voltage set at 2.63V, the MAX6314US26D2-T is optimized for applications that operate with a 2.6V power supply but is also well-suited for a range of voltages around this value. This precision monitoring helps ensure that the system microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

One of the key features of this supervisory circuit is its ability to assert a reset signal whenever the VCC supply voltage falls below the preset threshold. The reset signal remains asserted for a minimum of 140ms after VCC rises above the reset threshold, providing ample time for the system to stabilize before the processor begins operation. This timing precision is achieved through an internal timer, which eliminates the need for any external components.

The MAX6314US26D2-T comes in a compact, 4-pin SOT-143 package, making it an excellent choice for space-constrained applications. Its low power consumption, typically 1.5µA at VCC = 3.3V, allows for efficient system design, which is particularly beneficial in portable and battery-powered devices.

Furthermore, the device includes additional features such as a debounced manual reset input. This allows for a manual override of the automatic reset, providing designers and end-users with more control over the reset function. The manual reset function can be triggered via an external pushbutton or logic signal, offering flexibility in system design and user interaction.

In summary, the MAX6314US26D2-T from Maxim Integrated is a robust and reliable solution for system monitoring and reset management. Its precision voltage monitoring, extended reset timing, low power consumption, and manual reset option make it an excellent choice for maintaining the integrity and reliability of microprocessor-based systems.
