Power management integrated circuits (PMIC) are widely used in a variety of electronic systems and applications. PMICs help to regulate, manage and protect the power supply in an application or system. They typically provide the functions of voltage regulation, current regulation, protection, monitoring and communication. Supervisors, a type of PMIC, are used to detect, monitor and respond to system faults or abnormal operating conditions in an electronic application. S-80157BNMC-JHI-T2 is a type of supervisor PMIC manufactured by SI-EN Technology Co., Ltd., a Taiwan-based integrated circuit design and production company. The S-80157BNMC-JHI-T2 has numerous applications in areas such as automotive, communications, industrial and consumer electronics. It is specifically designed to protect Microcontroller Unit (MCU) devices from damage caused by overcurrent, overvoltage, ESD and other potential destructive conditions.The S-80157BNMC-JHI-T2 utilizes several advanced technologies to ensure its dependable performance and provide a high level of protection for MCU devices. For example, it has an internal EEPROM that stores voltage threshold levels and other critical parameters. This EEPROM can be programmed remotely via a serial peripheral interface (SPI) or manually with an external SPI programmer. The S-80157BNMC-JHI-T2 also has a built-in thermal shut-down circuit that can be programmed to protect the device in high temperature environments. In addition, the supervisor PMIC has a built-in power pre-fault signal. This signal provides a warning of a possible over-current condition before it occurs, allowing the controlling MCU device to adjust power settings in order to avoid potential damage or system crashes.The S-80157BNMC-JHI-T2 also provides several additional features to help ensure the performance of MCU systems. For example, it has an adjustable reset signal output for system reset and a low-power comparator for reset timer functions. In addition, it has a wide operating temperature range of -40 to 125℃, making it suitable for a variety of applications.The working principle of the S-80157BNMC-JHI-T2 is based on the comparison of the voltage of the power supply under test and the predefined value stored in the device’s EEPROM. Every time the power supply voltage is changed, the S-80157BNMC-JHI-T2 will compare it with the EEPROM value to determine whether it exceeds the predefined limit. If the power supply voltage is higher than the set value, the device will issue a reset signal to the controlling MCU in order to correct the overvoltage condition.In summary, the S-80157BNMC-JHI-T2 is a highly reliable and versatile supervisor PMIC that can effectively protect MCU devices from damage caused by various system faults and destructive conditions. It combines advanced features such as an internal EEPROM for storing critical parameters, a built-in thermal shut-down circuit and a power pre-fault signal to help ensure a reliable and dependable performance. The S-80157BNMC-JHI-T2 can be used in a variety of applications, such as automotive, communications, industrial and consumer electronics.
