Power management integrated circuits (PMICs) are an important component in electronic systems, and supervisors are a particular subgroup of them. The S-80841CLNB-B62T2G is one of these supervisors that is used in a broad range of applications thanks to its wide variety of features. This article will describe the application fields of the S-80841CLNB-B62T2G in detail and explain its working principle.

The S-80841CLNB-B62T2G is a supervisor chip designed to provide reliable reset signal based on a variety of conditions. It is suitable for a wide range of applications, such as automotive electronics, industrial control systems, computer systems, and more. In addition, it is a highly integrated device, combining reset signal current sourcing, overvoltage protection, power-on reset signal generation, internal power control, and other functions in the same package.

The S-80841CLNB-B62T2G can be used for power sequencing in automotive electronics, electric vehicles, and other systems. It can be used to ensure proper start-up of systems, by supplying the power-on reset signal for the microprocessors, ASICs, and FPGAs in the system. This chip also includes a Power-On Reset (POR) and overvoltage protection feature. The POR detects whether the system is on or off, and the overvoltage protection prevents overvoltage spikes, both of which will ensure reliable start-up and safe operation of the system.

The S-80841CLNB-B62T2G also has an integrated high-accuracy voltage detector, which is used to accurately monitor the system’s voltage level. This voltage monitor can detect undervoltage (UVLO) conditions and generate an active reset signal accordingly. It offers excellent accuracy, and the reset delay time can be adjusted according to system specifications.

In addition to voltage monitoring and protection, the S-80841CLNB-B62T2G also includes a watchdog timer that monitors system activity and ensures the system is running reliably. If the watchdog timer detects a malfunction in the system, it will generate a reset signal to reset the system. This feature will protect the system from any unforeseen malfunctions.

The S-80841CLNB-B62T2G also has two different reset memory circuits. The first reset memory circuit is used to store the system’s reset status and then output a reset signal to reset the system when the power is first turned on. The second reset memory circuit is used to store the watchdog timer status and can detect any malfunctions in the system, even if the power is turned off.

The working principle of the S-80841CLNB-B62T2G is relatively simple. It consists of three main components: a voltage monitor, a watchdog timer, and two reset memory circuits. When the power is first turned on, the voltage monitor detects the voltage level and then if the voltage is above a certain threshold, the watchdog timer will start to monitor the system activity. The watchdog timer monitors the system and checks for malfunctions, and if a problem is found, it will generate a reset signal and reset the system.

The two reset memory circuits then store the reset status of the system and output a reset signal when the power is first turned on. This reset signal will reset the system and reinitialize the microprocessors, ASICs, and FPGAs. If the watchdog timer detects a malfunction, it will generate a different reset signal to reset the system.

In conclusion, the S-80841CLNB-B62T2G is a highly useful supervisor chip with a wide variety of features. It is suitable for a broad range of applications, such as automotive electronics, electric vehicles, computer systems, and more. It has a comprehensive set of features, such as voltage monitoring and protection, power-on reset signal generation, overvoltage protection, integrated high accuracy voltage detector, internal power control, and watchdog timer. By understanding its working principle, it is clear to see why the S-80841CLNB-B62T2G is such a popular choice for supervision.
