Working Principle

The STM1403ATNQ6F is a multilayer ceramic type of supervisor with its main components consisting of a voltage regulator and a reset generator. There are several types of inputs which can be monitored, including motor current, battery voltage, processor’s temperature, and more. It also has a wide range of voltage threshold levels in its input monitor, enabling customized protection levels depending on the application. In addition, the supervisor is able to detect multiple parameters with its onboard I/O detector.

The reset generator is the key element of the STM1403ATNQ6F’s functioning. It is responsible for generating a reset signal when any of the monitored parameters reach an unnacceptable value. This reset signal is then sent to the system’s microcontroller, halting all operations and resetting the system. This ensures continued protection of the system components even when an unexpected event occurs.

Lastly, the STM1403ATNQ6F employs several failure protection mechanisms, making it the best choice for advanced protection and stability. For instance, the power supply monitor automatically shuts the system down if any of its input parameters reach dangerously low levels. Similarly, the I/O detector is used to detect overcurrent and short circuit conditions, to further protect the system from damaging events.

These features and capabilities make the STM1403ATNQ6F one of the most reliable and flexible multilayer ceramic supervisors on the market. As such, it is the ideal choice for manufacturers who need an integrated circuit to protect their systems from unexpected events and failures.
