Maxim Integrated MAX6320PEUK29DY Microprocessor (µP) Supervisory Circuit

The MAX6320PEUK29DY is a high-precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring and battery control functions.

This supervisory IC ensures that the µP and its associated circuitry are reset properly during power-up, power-down, and brown-out conditions. The MAX6320PEUK29DY comes in a compact SOT23 package, making it ideal for space-constrained applications that require the highest level of integration.

Key features of the MAX6320PEUK29DY include:

• Voltage Monitoring: This device has a preset threshold voltage of 2.93V, which is ideal for monitoring 3.3V power supplies. It ensures that the system microcontroller is held in reset until the system voltage has stabilized.
• Manual Reset Input: It includes a manual reset input that allows for a system reset to be triggered with an external switch or logic signal, providing an additional layer of system control.
• Low Power Consumption: The device is designed for low power consumption, making it suitable for battery-powered applications. It has a typical supply current of only 1µA, which helps to extend battery life.
• Reset Output: The active-low reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring a proper system reset. The output type is push-pull, which provides a strong signal to connected components.
• Temperature Range: The operating temperature range of -40°C to +85°C allows the device to perform reliably in a wide range of environments.

With its precision voltage monitoring and low power consumption, the MAX6320PEUK29DY is an excellent choice for portable devices, computers, controllers, and intelligent instruments. It helps to safeguard your system by providing a reliable reset signal, ensuring that your microprocessor starts up correctly every time the power is applied or restored.

Maxim Integrated's commitment to quality and reliability is evident in this supervisory circuit, making it a smart choice for designers looking to enhance system stability and prolong operational lifespan.
