The DS1816R-20+T&R from Maxim Integrated is a precision microprocessor (µP) supervisory circuit designed to monitor the supply voltage of digital systems and provide a significant level of system reliability through reset and watchdog functions. This versatile component is essential for systems that require a high degree of operational stability and protection against power supply inconsistencies.

Key Features

• Supply Voltage Monitoring: The DS1816R-20+T&R actively monitors the system's supply voltage and ensures it remains within specified thresholds for reliable operation.
• Programmable Reset Thresholds: It offers programmable reset threshold levels, allowing designers to tailor the reset response to specific system requirements.
• Watchdog Timer: A built-in watchdog timer provides an additional layer of system integrity by ensuring that the system software is operating correctly. If the software fails to provide a periodic signal to the watchdog, a system reset is initiated.
• Automatic Reset Generation: In the event of a supply voltage drop below the designated threshold or a watchdog fault, an automatic reset signal is generated to restore the system to a known state.
• Low Power Consumption: This component is designed for low power consumption, making it suitable for battery-powered and energy-efficient applications.
• Compact Packaging: The DS1816R-20+T&R is available in a space-saving SOT-23 package, which is ideal for space-constrained applications.
