PMIC (power management integrated circuit) supervisors typically play an important role in ensuring system reliability and maintaining operational data integrity. They are used to monitor voltage and temperature levels, reset systems, provide delayed shutting off of peripheral devices, and initiate system recovery operations when necessary. The MCP1321T-26GE/OT is a versatile PMIC supervisor with a wide range of applications for automotive, industrial and consumer products.

The MCP1321T-26GE/OT is a CMOS-based low-power digital supervisor circuit providing three complementary functions: precision monitoring of voltage; input debouncing; and system reset control. It has an operating voltage range of 2.9 - 5.5V, comes with a wide preset temperature range of -40°C to +125°C, and an accuracy of 0.75%. It also has a low power dissipation characteristic and can be applied to a wide range of applications.

In addition to its various features, the MCP1321T-26GE/OT can be used to monitor the voltage levels of up to three system voltages and up to four power supplies. The device triggers a reset signal when any of the monitored voltages falls below a preset user-defined threshold. With this ability, it helps maintain correct operations and system data integrity.

The MCP1321T-26GE/OT also helps in delaying the power-off transition of peripheral devices. It has a dedicated time-out feature that allows it to shut down the power to peripherals for a configured time so that pending operations can be completed before resetting the system. This function provides additional safety and stability for the system.

In order to ensure its robust operation, the MCP1321T-26GE/OT contains an embedded watch dog timer (WDT) which helps detect events that could cause unexpected system hang-ups or lock-ups. The WDT is used to reset the system when the software fails to execute the required reset command within the preset window of time. This ensures that the system remains stable, even if a certain event causes the system to stop working unexpectedly.

In order to recover from any unexpected system failures, the MCP1321T-26GE/OT has a system recovery feature, which can be configured to initiate a system reboot or a system restoration process. This feature allows the user to use pre-established sequences to automatically execute system recoveries, allowing the user to quickly get back to a working state.

In addition to its monitoring, resetting and system recovery capabilities, the MCP1321T-26GE/OT also provides protection against ESD, with an ESD protection capability of up to 8 kV HBM. The device also has a wide range of developing tools, such as evaluation boards and development tools, to reduce development and manufacturing costs.

The MCP1321T-26GE/OT is a versatile and powerful PMIC supervisor, suitable for a wide range of applications. Its features, along with its various development tools, make it an excellent choice for automotive, industrial and consumer electronic applications. It helps to ensure system reliability and data integrity, allowing for safer and more secure operations.
