PMIC - Supervisors is a category of power management integrated circuit (PMIC), which is used to supervise various power rails and provide protection for systems or devices from inappropriate or unexpected supply behaviors or conditions. S-80156CNPF-JLHTFG is a type of PMIC - Supervisors device which is desirable for its multiple voltage input, high accuracy voltage monitoring, and built-in timer & reset for systems or devices protection.

S-80156CNPF-JLHTFG Application Field

S-80156CNPF-JLHTFG is widely used in security-required system monitoring, especially applied in Radio Frequency Identification (RFID) systems, point-of-sale (POS) systems, and Automated Teller Machines (ATMs). It is a very successful PMIC - Supervisors device with its excellent features, such as advanced circuitry and integrated single-chip advanced security technology, which is highly suitable for systems or devices that need high safety assurance.

Functions of S-80156CNPF-JLHTFG

S-80156CNPF-JLHTFG is composed of two functional blocks: a window watchdog and a reset controller. The first function of the S-80156CNPF-JLHTFG is to supervise that if the system or device is running correctly. The window watchdog will monitor whether or not the system or device is running correctly in every predefined time period. If the system or device is running correctly, then a reset will be generated. The reset controller will then reset the system or device to return it to the normal condition, and keep reset until the system or device resumes to function normally.

The second function of S-80156CNPF-JLHTFG is to provide protection for the system or device in case that the system or device is running abnormally. The window watchdog will monitor the system or device by comparing the input voltage with the voltage that is pre-defined as a "threshold voltage," if the voltage difference is larger than the threshold voltage, then the reset controller will generate a reset to the system or device.

Work Principle of S-80156CNPF-JLHTFG

The work principle of S-80156CNPF-JLHTFG is quite simple. First, the window watchdog will connect to the system or device and monitor the operating status in a predefined time period. During the time period, if the power condition of the system or device is normally, a reset will be generated by the window watchdog, and the reset controller will control the system or device to return to the normal state. Alternatively, if the voltage is odd or if the voltage difference is larger than the threshold voltage, then a reset will also be generated by the reset controller.

In summary, S-80156CNPF-JLHTFG is a PMIC - Supervisors device which is designed to supervise various power rails and provide protection to systems or devices. It has two functional blocks of window watchdog and reset controller and they are responsible for monitoring the operation status of the system or device, and reset it to the normal condition in case it is not normal. The application field of S-80156CNPF-JLHTFG is various security-required system monitoring, such as ATMs, RFID systems and POS. With its excellent features, it is highly suitable for the safety assurance of system or device.
