MAX6328UR26+T - Maxim Integrated

The MAX6328UR26+T from Maxim Integrated is a high-quality, precision microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring.

This device is particularly suitable for portable and battery-powered applications due to its low power consumption and small footprint. The MAX6328UR26+T offers a preset V_CC reset threshold voltage of 2.6V, which is ideal for 3V powered circuits, ensuring that the system microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

Key Features:

• Reset Threshold Voltage: Preset to 2.6V, suitable for 3V systems.
• Low Power Consumption: Ideal for battery-operated devices, enhancing battery life.
• Immune to Short V_CC Transients: Provides reliable monitoring and prevents false resets.
• Push-Pull RESET Output: The active-low, push-pull output quickly drives the reset signal to the µP.
• Temperature Range: Operates over an extended temperature range, making it versatile for various environments.
• Small SOT23 Package: Space-saving design, perfect for compact system designs.

With its built-in glitch immunity, the MAX6328UR26+T ensures that the µP reset input will remain in the reset condition for a minimum of 140ms after V_CC has risen above the reset threshold level. This feature provides the system with ample time to stabilize during power-up.

The device comes in a tiny SOT23-3 package, which is highly beneficial for space-constrained applications. Additionally, it is specified over the full industrial temperature range (-40°C to +85°C), which allows its use in harsh environments.

In summary, the MAX6328UR26+T from Maxim Integrated is a robust, low-power, and compact solution for reliable voltage monitoring in digital systems and microprocessor-based applications, ensuring proper system reset and operation.
