Since their invention in the 1970s, supervisors (Supervisory circuits) have been among the most important power management integrated circuits (PMICs) in the fabrication of electronic system designs and applications. The S-80156ANPF-JDHTFG is a unique PMIC supervisor chip that offers a wide range of features and functionalities. This article will discuss the application field and the functional components of the S-80156ANPF-JDHTFG and will address its working principle.

The S-80156ANPF-JDHTFG is an ultra-small package supervisor for automotive, consumer, and industrial applications. This PMIC Supervisors is designed with a wide range of adjustable features including watchdog timers, reset comparators and reset logic. Embedded in this supervisor chip are two timers that are useful for timing inversely proportional voltage and temperature derating as well as keeping track of the overall system’s performance. The chip also features an 8-bit configurable logic cell that is used for resetting the system and isolating the power components when it goes out of spec.

The S-80156ANPF-JDHTFG application fields range from automotive to consumer electronics. Most notably, this particular supervisor has been used in advanced driver assistance systems (ADAS) to power the control systems of vehicles. Other applications are in the consumer electronics model, where it is used to control the power management systems of television sets, home appliances, and other household items. This PMIC supervisor chip can also be used in remote automatic Solar PV systems and medical systems.

In terms of the working principle of the S-80156ANPF-JDHTFG, it primarily relies on the two timers embedded within the chip. The shorter timer is called the watchdog timer and it is responsible for providing periodic reset signals whenever its configured parameters are met. The longer timer is referred to as the soft startup timer, which is responsible for powering the system in order for the watchdog timer to properly send its reset signals.

When an irregularity is detected in the system, the watchdog timer will send a short-term reset signal. This short-term reset signal is used by the chip to deactivate all the power components, isolate them from each other, and reset them a few milliseconds afterwards. This helps discourage the occurrence of surges or drops in the system’s current or voltage, which can potentially cause catastrophic damage.

On the other hand, the soft startup timer is responsible for the orderly startup of the power components. This timer consistently monitors the current and voltage of the system and sends pulses to ensure that the components receive the correct power. This is done in order to avoid overdriving components and to protect against any erroneous system operation.

In summary, the S-80156ANPF-JDHTFG PMIC Supervisors is a cutting-edge power management chip designed for automotive, consumer, and industrial applications. This chip features watchdog timers and reset logic components to ensure proper and efficient system operations. The timers embedded in this chip work in tandem to monitor the system’s current and voltage and to ensure the proper operation of the power components.
