STM802LM6F Integrated Circuits (ICs)

STM802LM6F is a Microcontroller System Reset Supervisor and a member of STMicroelectronics’ STM8 family. It is a low-cost and low-power integrated solution designed to support a wide system health and fault-tolerance monitoring and resetting capability. This product is suitable for the needs of low-power systems, such as portable handheld devices, digital home appliances, and automotive systems. The STM802LM6F is integrated with a Watchdog, manual reset input and RESET output. It features high accuracy, excellent immunity against power supply variation, SET/RESET functions, asynchronous operation, and low power consumption.

The main application fields of STM802LM6F are in portable and embedded systems, digital home appliance, healthcare, automotive and industrial application. The STM802LM6F is designed to be proved an ultimate source of microcontroller’s reset signal in fault tolerant environments while also providing a low-cost reset function across a wide range of applications. The STM802LM6F also includes a comprehensive set of fault monitors and detections. This includes input under-voltage (UV) fault, output overvoltage (OV) fault, and push-pull output fault. It also provides a robust reset capability to initiate any system reset event in fault-tolerant environments.

The working principle of STM802LM6F is based on three main points. First, the RESET output initiates a reset to the microcontroller when triggered. Then, the STM802LM6F monitors the power-on voltage of the system and maintains the proper reset timing regardless of power supply variation. Finally, when the power-up voltage is out of tolerance for longer than three seconds, the STM802LM6F will provide a reset signal to the system. This ensures that the system remains in a consistent and healthy state.

The STM802LM6F offers several advantages over other solutions in the same category. The main advantages are its low power consumption, high accuracy, wide input voltage range, excellent immunity against power supply variation, SET/RESET functions, and asynchronous operation. All of these features are integrated into a small footprint package that provides flexible solutions for different types of systems.

The STM802LM6F is part of the STM8 family of products, providing an excellent solution to monitor and reset faults in embedded systems. It is suitable for low-power systems and provides robust reset capabilities in fault-tolerant environments. It offers low power consumption, high accuracy, wide input voltage range, excellent immunity against power supply variation, SET/RESET functions, and asynchronous operation. Furthermore, the STM802LM6F provides a cost-effective solution for any microcontroller system reset supervisor and health monitor.
