Product Overview: MAX6866UK23D3L+T from Maxim Integrated

The MAX6866UK23D3L+T is a microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low power consumption, making it an essential component for portable and battery-powered applications. This supervisory IC ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions.

One of the key features of the MAX6866UK23D3L+T is its precise factory-set V<sub>CC reset threshold of 2.3V, which caters to systems that operate at lower voltages. The device maintains system integrity by monitoring the supply voltage and asserting a reset signal whenever the V<sub>CC supply voltage falls below the threshold. The reset output remains asserted for a minimum reset timeout period after V<sub>CC rises above the reset threshold, ensuring the system has adequate time to stabilize.

The MAX6866UK23D3L+T is available in a compact SOT23-5 package, making it suitable for space-constrained applications. It operates over a wide temperature range of -40°C to +125°C, which allows for deployment in environments with varying temperature conditions. Furthermore, its low supply current of only 7.5µA (typical) makes it an energy-efficient choice for battery-operated devices.

This supervisory circuit also includes a manual reset input that enables a processor or a user to initiate a system reset. The device's active-low, open-drain reset output can interface directly with various logic levels, offering versatility in system design.

The MAX6866UK23D3L+T is part of Maxim Integrated's extensive line of µP supervisory circuits that provide monitoring of power supply voltages and system health, which are critical for maintaining the performance and reliability of electronic systems. It is ideal for applications in consumer electronics, portable devices, and any system that requires a high level of voltage monitoring precision and reliability.

In summary, the MAX6866UK23D3L+T from Maxim Integrated is a robust, low-power µP supervisory circuit that provides vital monitoring and protection for digital systems. Its precision voltage monitoring, small package size, and low power consumption make it an excellent choice for a wide range of applications.
