The MAX690MJA/883B is a high-quality microprocessor supervisory circuit produced by Maxim Integrated, a renowned manufacturer of innovative analog and mixed-signal products. This supervisory circuit is specifically designed to provide reliable monitoring and reset functions for microprocessor (µP) systems, ensuring that the systems operate correctly and protect against power failures or anomalies.

Key Features

• Voltage Monitoring: The device is capable of monitoring the power supply voltage levels to ensure that they remain within acceptable thresholds for stable µP operation.
• Power-On Reset: Upon power-up, the MAX690MJA/883B generates a reset signal to the µP, which holds the processor in a reset state until the power supply has stabilized.
• Manual Reset: A manual reset feature allows the user to initiate a system reset, providing an additional layer of control.
• Battery Backup Switching: In the event of a power failure, the device automatically switches to a backup battery to maintain volatile memory and real-time clock operations.
• Watchdog Timer: The integrated watchdog timer ensures that the µP does not hang in an unresponsive state by periodically resetting the system if the µP fails to provide a regular heartbeat signal.
• Low Power Consumption: Designed with power efficiency in mind, the MAX690MJA/883B is ideal for battery-powered applications.
