PMIC (Power management integrated circuit) supervisors, also known as system supervisors, are one type of critical integrated circuits that can be used to protect electronic systems from unforeseen critical faults that could lead to catastrophic failure. The SP690SCN-L series of PMIC supervisors are specifically designed to provide very low power system monitoring, allowing the host system to stay fully functional even during circuit failure or system discharges.

As its function implies, the SP690SCN-L is a supervisor IC that is capable of monitoring system voltages, current and temperatures. This IC is specifically designed for use in applications where accuracy and low power consumption are key requirements. The logic for the SP690SCN-L is designed to detect overvoltage, undervoltage and/or over temperature events, based on user-defined threshold values. It can also provide a range of outputs such as digital, open-drain or open-collector outputs.

When the SP690SCN-L detects an overvoltage or undervoltage event, the supervisor IC will trip its internal circuits, triggering the reset function. This reset feature is critical in protecting the host system against potential circuit failure or system discharges, as it ensures that the power supply is in a safe and stable state before the system is re-powered. Additionally, the SP690SCN-L can be configured to operate in a variety of modes, including manual reset mode, watchdog timer, and software polling.

The SP690SCN-L is also capable of monitoring temperatures, which can be helpful in detecting thermal issues. The built-in on-chip and external temperature detection circuits can accurately detect temperatures using digital or analog techniques. When the set temperature threshold is crossed, the IC will trigger an output signal, notifying the system to take the necessary steps to prevent thermal damage.

The SP690SCN-L is highly versatile, and can be used in a variety of applications such as industrial, automotive, battery management, wearable/hearable devices, consumer electronics and more. In battery management applications, for example, the SP690SCN-L can be used to help protect against overcharging and overheating, thereby improving battery life and performance. In industrial systems, the SP690SCN-L can be used to monitor system load currents, thereby reducing the risk of equipment breakdown due to sudden overloads.

Overall, the SP690SCN-L is a highly versatile and reliable system supervisor IC, offering accurate monitoring of system voltages, current, and temperatures. Through its built-in reset feature and temperature detection circuits, the IC ensures that the system is protected against unexpected faults and thermal damage. This makes it an ideal solution for applications where accuracy and low power consumption are key requirements.
