The MAX811MCPA from Maxim Integrated is a compact, highly reliable voltage supervisor IC designed to monitor power supplies in microprocessor and digital systems. It provides a precise, low-power method for monitoring a single system supply voltage. This device is particularly well-suited for battery-powered applications due to its low power consumption and small footprint.

Key Features

• Voltage Monitoring: The MAX811MCPA ensures that the system voltage does not fall below a predefined threshold, thereby safeguarding sensitive electronic components from improper operation or damage due to undervoltage conditions.
• Reset Output: It provides an active-low reset output, which holds the microprocessor in the reset state until the system voltage stabilizes. This feature ensures a reliable system startup and operation.
• Programmable Reset Timeout: Designers can program the reset timeout duration to meet specific system requirements, allowing for a flexible and tailored reset response.
• Low Power Consumption: With its quiescent current typically under 5 µA, this IC is ideal for power-sensitive applications, extending battery life and reducing overall power usage.
• Compact Package: The MAX811MCPA comes in a small 8-pin μMAX package, making it an excellent choice for space-constrained applications.
