The DS1814BR-10-U is a versatile micro-monitor chip from Maxim Integrated, designed to provide reliable system monitoring and control for microprocessor (µP) systems. This compact and efficient device offers a multifaceted approach to safeguarding system integrity through its reset and watchdog timer functionalities.

Key Features

• Automatic Reset: On power-up, the DS1814BR-10-U generates a reset pulse, ensuring the µP starts from a clean state. It also monitors the power supply voltage and asserts a reset to the µP during brownout conditions, maintaining system stability and preventing data corruption.
• Programmable Watchdog Timer: The built-in watchdog timer serves as an operational safeguard, compelling the µP to service it periodically. If the µP fails to do so within a preset time frame, the DS1814BR-10-U assumes a system fault and issues a reset, prompting a system recovery.
• Manual Reset Input: An external manual reset input allows for system resets on demand, providing additional flexibility and control for system maintenance or emergency interventions.
• Voltage Monitor: The device features a precise voltage monitor that keeps tabs on the supply voltage, ensuring that the system operates within safe voltage thresholds.
