ON Semiconductor's MAX812REUS-T: A Reliable Microprocessor Monitoring IC

ON Semiconductor's MAX812REUS-T is a precision microprocessor (μP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required for controlling system reset and power failure warning functions. This versatile component is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, and portable battery-powered electronics.

The MAX812REUS-T supervisory circuit offers several key features that make it an essential component for any system requiring robust power monitoring. It incorporates a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted until the VCC voltage reaches the reset threshold level and keeps it asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring a proper system reset during power up or down.

Key Features and Benefits:

• Precision Monitoring: The device has a factory-trimmed reset threshold voltage, which ensures accurate monitoring of the power supply.
• Low Power Consumption: With a low supply current of 17μA, the MAX812REUS-T is an energy-efficient choice for battery-operated devices.
• Wide Operating Voltage Range: It operates over a wide voltage range of 1.2V to 5.5V, making it suitable for various digital systems.
• Manual Reset Input: The inclusion of a manual reset input provides an additional layer of control, allowing for a system reset at any time.
• Compact SOT-143 Package: The device comes in a small, surface-mount SOT-143 package, which is beneficial for space-constrained applications.

With its combination of features, the MAX812REUS-T from ON Semiconductor is an excellent choice for system designers looking for a reliable and efficient way to protect their digital systems from the dangers of unpredictable power supplies. The device's precision voltage monitoring capability and low power consumption make it an indispensable component for maintaining the integrity and stability of a wide array of electronic products.

Whether you are designing a new system or upgrading an existing one, the MAX812REUS-T provides the security and peace of mind that comes with knowing your system's power supply is under constant surveillance. Its ease of integration and robust feature set ensure that your products will operate reliably and efficiently, safeguarding your data and hardware against power-related anomalies.
