The MAX6328UR26 is a highly compact, precision microprocessor (µP) reset circuit device from Maxim Integrated designed to monitor power supplies in digital systems. It provides a reliable solution for systems that require an active-low reset signal when the supply voltage drops below a preset threshold, ensuring that the µP and its peripherals are reset properly and operate optimally once power is restored.

Key Features

• Precision Factory-Set V<sub>RESET: The reset threshold voltage is precisely set at the factory to 2.6V, which helps to maintain system reliability without the need for external adjustments.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6328UR26 consumes minimal power, which is critical for extending battery life in portable devices.
• Manual Reset Input: A manual reset input allows for a system reset to be triggered with an external signal, providing additional flexibility and control.
• High Reset Output Sink Current: Capable of sinking up to 5.5µA, this device can directly drive the reset pin of most microprocessors.
• Immune to Short V<sub>CC Transients: The MAX6328UR26 is designed to ignore brief drops in supply voltage, preventing unnecessary resets due to transient conditions.
• Compact SOT23 Packaging: The ultra-small SOT23 package makes it ideal for space-constrained applications, without compromising on performance.

Applications

The MAX6328UR26 is suitable for a wide range of applications, particularly those that require high reliability and extended battery life. It is commonly used in:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Industrial Controllers
• Handheld Instruments

With its combination of low power consumption, precision monitoring, and compact form factor, the MAX6328UR26 is an excellent choice for designers looking to enhance system stability and extend operational life in their digital systems.
