MIC812JU TR belongs to the PMIC - Supervisors category, and it is designed with a range of functions and features for various applications. This product combines a wide range of features, including brown-out protection, internal current limit, temperature supervisor, power-on reset, and low quiescent current. It includes a comparator that can sense changes in voltage and generate an interrupt, as well as a watchdog timer and power-on reset circuit.

Application Field

The MIC812JU TR is suitable for applications that require superior performance and reliability, such as motor control, automotive, and industrial control applications. The device is designed to accommodate both 3V and 5V logic inputs and offers enhanced protection features for input and output signals such as undervoltage protection, overcurrent protection, and hysteresis. Furthermore, the product is also suitable for communication interface ICs, DC/DC converters, signal inputs, and signal outputs.

Working Principle

The MIC812JU TR works by monitoring the voltage of the power supply and providing a reset signal when the voltage falls below a certain level. This reset signal is then used to initiate a reset sequence to all of the system’s components. The reset signal is generated through an internal comparator, voltage monitor, and reset generator. The voltage monitor senses changes in the power supply voltage and compares it to a predefined level. When the monitored voltage falls below this level, the reset signal is generated.

In addition to providing over-current and undervoltage protection, the MIC812JU TR also offer a temperature watchdog circuit designed to detect excessive temperatures that may result in component damage. This circuit monitors the temperature of the system and generates a reset signal if the temperature exceeds a certain level. This reset signal is then used to shut down the system in order to prevent component damage.

Conclusion

The MIC812JU TR provides an integrated range of features that make it suitable for a wide range of applications, including motor control, automotive, and industrial control applications. The device is designed to provide superior performance and reliability, and features such as overvoltage and undervoltage protection, hysteresis, and a temperature watchdog circuit. In addition, the MIC812JU TR includes a comparator that can sense changes in voltage and generate an interrupt, as well as a watchdog timer and power-on reset circuit.
