The Maxim Integrated DS1812-10+ is a robust, versatile microprocessor (µP) supervisory circuit designed to monitor the power supply and microprocessor activity in digital systems. It provides essential protective functions to enhance system reliability and prevent data corruption during power-up, power-down, and brown-out conditions.

Key Features

• Supply Voltage Monitoring: The DS1812-10+ actively monitors the supply voltage, ensuring that it remains within acceptable thresholds for reliable operation of digital systems.
• Programmable Reset Thresholds: This device features precision temperature-compensated voltage reference and comparator circuitry to monitor VCC for under-voltage conditions. When VCC falls below the reset threshold, the reset signal is asserted.
• Automatic Reset Generation: Upon detecting a fault condition, the DS1812-10+ generates a reset signal for a minimum of 150ms after VCC rises above the reset threshold, ensuring the µP starts up in a known state.
• Manual Reset Input: A manual reset input allows for a system reset to be triggered with an external switch or logic signal, providing additional system control.
• Low Power Consumption: Designed for energy-efficient operation, this supervisory circuit is ideal for portable and battery-powered applications.
• Compact Package: The DS1812-10+ is available in a space-saving 3-pin TO-92 package, making it suitable for use in space-constrained applications.

Applications

The DS1812-10+ is widely used in various applications that require reliable voltage monitoring and processor supervision. Some common applications include:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Devices
• Industrial Controllers
• Telecommunication Systems
