Power management integrated circuits (PMIC) are important for controlling and regulating the performance and power of circuit boards. Supervisors are a type of PMIC used to monitor the operating conditions of a system, provide system reset, and indicate when operating conditions are outside of the specified operating range. This article focuses on the S-80956CLPF-G7STFG supervisor and its application field and working principle.

The S-80956CLPF-G7STFG is a 3.0V to 5.5V nanosecond reset supervisor with watchdog timer and power-on reset (POR) functions. It is a robust and reliable device, which is widely applicable to systems under extreme shock and vibration. This device is optimized for operation with high-speed microcontrollers and CPUs, as indicated by its minimal propagation delay of 900 ns. This device has several output configurations, including open-drain or active-high outputs with precision reset thresholds, adjustable reset active time delays, a watchdog timer with selectable timout periods, and an external reset input.

The S-80956CLPF-G7STFG is designed for a wide range of applications, one of them being automotive systems. The device meets the Automotive Electronics Council’s AEC-Q100 standard which means that it can withstand extended temperature ranges, shock and vibration that is typical in automotive environments. Also, with its fast reset response and adjustable reset active delay time, it can reset the system quickly and keep the system running in a stable condition. Additionally, its ultra-low-power consumption make it ideal for portable applications.

The working principle of the S-80956CLPF-G7STFG is simple. It uses multiple of different input signals to detect the system’s working conditions and trigger reset events when required. For example, the power-on reset (POR) function keeps resetting the system to its default state on power up. The watchdog timer is used to detect abnormal conditions and reset the system when needed. The external reset input gives the user another line for resetting the system manually. The S-80956CLPF-G7STFG also has an over-voltage monitor which helps to detect over-voltage events and reset the system before damage has occurred.

In conclusion, the S-80956CLPF-G7STFG is a 3.0V to 5.5V nanosecond reset supervisor with watchdog timer and power-on reset (POR) functions. It is designed for automotive and portable applications with its fast reset response, adjustable reset active delay time, and ultra-low-power consumption. The working principle and applications of this device has been discussed. Therefore, the S-80956CLPF-G7STFG is a suitable and robust solution for providing reset protection in automotive, portable, and general-purpose applications.
