The MAX6804US46D3+ is a high-quality microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. This device ensures that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6804US46D3+ is particularly suitable for portable and battery-powered applications due to its low power consumption and compact size.

Key Features

• Voltage Monitoring: The MAX6804US46D3+ monitors the power supply voltage and keeps the microprocessor in reset until that voltage reaches a stable operating level. It maintains the reset output for approximately 140ms after the voltage exceeds the reset threshold, ensuring the system has a stable startup.
• Low Power Consumption: With its low supply current of 1.1µA, this device is energy-efficient, making it ideal for battery-powered applications where power conservation is critical.
• Precision Voltage Threshold: The reset threshold is factory-set to 4.63V, providing a precise monitoring solution without the need for external components.
• Manual Reset Input: It includes a manual reset input that allows the user to initiate a reset, offering additional control over the system's operation.
• High Reset Output Sink Current: Capable of sinking up to 20mA, the reset output ensures compatibility with a wide range of microprocessors and other digital ICs.
• Compact SOT23 Packaging: The device comes in a small SOT23-3 package, saving space on the PCB and making it suitable for high-density circuit designs.
