Maxim Integrated MAX6339KUT+T - Precision, Low-Power, 5-Pin SOT23, Single/Dual-Voltage µP Reset Circuits

The Maxim Integrated MAX6339KUT+T is a highly reliable microprocessor (µP) reset circuit designed to monitor single or dual system supply voltages. This precision, low-power device is packaged in a compact 5-pin SOT23, making it ideal for space-constrained applications. It is specifically engineered to maintain system integrity by monitoring the power supply levels and asserting a reset signal whenever a voltage drops below its preset threshold, ensuring that the µP or digital system resets cleanly during power-up, power-down, or brown-out conditions.

One of the key features of the MAX6339KUT+T is its factory-trimmed voltage thresholds, which offer high accuracy and stability over the entire operating temperature range. The device can monitor voltages as low as 1.8V, which is suitable for low-voltage operations in modern electronic systems. The reset output is available in both active-low and active-high configurations, providing design flexibility for different logic levels.

The device boasts a low supply current of only 1.2µA (typical), making it an excellent choice for battery-powered and portable devices where power conservation is crucial. Additionally, the MAX6339KUT+T features an integrated debounce circuit that filters out brief voltage dips, preventing false triggering of the reset signal and ensuring reliable operation.

The MAX6339KUT+T also includes a manual reset input, allowing system designers to trigger a reset externally whenever required. This feature is particularly useful for implementing system recovery procedures or for initiating a reset during maintenance without cycling the power supply.

Engineered with the quality and performance expected from Maxim Integrated, the MAX6339KUT+T is a robust solution for applications requiring precise voltage monitoring and reset functions. Its ease of integration, low power consumption, and small footprint make it a preferred choice for use in microcontrollers, computers, controllers, intelligent instruments, and portable electronics.

Overall, the MAX6339KUT+T represents a blend of performance, reliability, and convenience, ensuring that systems maintain optimal functionality and stability under varying power conditions.
