Maxim Integrated's MAX812SEUS+T Voltage Monitor

The MAX812SEUS+T is a compact, highly precise voltage monitor from Maxim Integrated, designed to ensure the reliability and stability of your electronic systems. This microprocessor (µP) supervisory circuit is engineered to monitor power supplies in digital systems, providing a significant layer of protection by triggering a reset during power-up, power-down, and brownout conditions.

This device is particularly suited for portable, battery-powered applications due to its low power consumption and small footprint. The MAX812SEUS+T comes in a space-saving SOT-143 package, making it ideal for space-constrained applications where board real estate is at a premium.

Key features of the MAX812SEUS+T include:

• Reset Threshold Levels: The device offers preset factory-calibrated reset threshold levels, ensuring that your system operates within safe voltage parameters.
• Reset Output: It provides an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level. This ensures a proper system reset and gives the power supply and processor time to stabilize.
• Low Power Consumption: With a typical supply current of only 17µA, this voltage monitor is an energy-efficient solution that minimizes the impact on your system's battery life.
• Wide Operating Voltage Range: The device supports a broad operating voltage range from 1.2V to 5.5V, making it versatile for various applications.
• Temperature Range: It operates over an extended temperature range from -40°C to +85°C, ensuring reliability and performance under varying environmental conditions.

Whether you're designing computers, controllers, intelligent instruments, or portable consumer electronics, the MAX812SEUS+T provides an essential layer of protection. By monitoring the supply voltage and ensuring your system operates within safe limits, this voltage monitor from Maxim Integrated helps to prevent data corruption and hardware damage due to unexpected power issues.

With its robust feature set and compact design, the MAX812SEUS+T is the go-to choice for engineers who demand reliability and precision in their power monitoring circuits.
