Maxim Integrated MAX6342SUT Microprocessor (µP) Supervisory Circuit

Maxim Integrated's MAX6342SUT is a compact, high-precision microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. Providing excellent circuit reliability and low cost, it ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6342SUT is ideal for battery-powered equipment, computers, controllers, and intelligent instruments.

The device comes in a small SOT23-6 package, making it perfect for space-constrained applications. It features a factory-trimmed reset threshold voltage, offering several options to match the voltage requirements of various µP systems. The reset output is guaranteed to be in the correct state for VCC down to 1.2V, which is essential for reliable operation of low-voltage systems.

One of the key features of the MAX6342SUT is its low power consumption, drawing only 1.2µA of supply current. This makes it an excellent choice for portable devices where battery life is critical. Additionally, the device provides a manual reset feature, allowing a reset to be asserted at any time by the user or the system, ensuring additional system control and flexibility.

The supervisory circuit offers a reset pulse width of 140ms (min), ensuring that the system has ample time to stabilize before the µP starts its operation. The MAX6342SUT operates over a wide temperature range of -40°C to +125°C, making it robust for industrial applications that may be exposed to extreme conditions.

In summary, the Maxim Integrated MAX6342SUT is a versatile and reliable solution for system monitoring and control. Its combination of low power consumption, small size, and precision monitoring capabilities make it an excellent choice for designers looking to enhance system stability and reliability in their digital and µP-based applications.
