Power Management IC (PMIC) supervisors are dedicated chips designed with the purpose of controlling and supervising system power. The S-80144ALMC-JA5T2U is a six-channel supervisor IC from Panasonic that can be used to protect an embedded system from short-circuits, over-voltages, under-voltages, and over-currents. This IC is capable of providing a high degree of accuracy and reliability with its tolerance for operating up to 300V and temperature range of -40°C to 85°C. It has several features, such as wide power supply range, power ON reset and enable features, accurate power ON detection, an independent watchdog timer, and an internal impedance matching network.

The main application field of the S-80144ALMC-JA5T2U is in embedded systems where low power and high accuracy are needed. It is commonly used in safety-critical applications, such as those found in telecommunications, automotive, and industrial systems, because it provides reliable power management. In addition, the S-80144ALMC-JA5T2U is also suitable for portable applications, such as those used in consumer electronics and handheld devices, due to its low power consumption.

The S-80144ALMC-JA5T2U works by monitoring the supply voltage and the system current. It senses any changes in supply voltage and current and sends an alert to the system. If the voltage or current falls below or exceeds a predetermined level, the supervisor responds quickly and sends a reset or an interrupt signal to the system. The supervisor also constantly monitors the temperature of the system and sends an alert if it rises above a preset value. The watchdog timer provides further protection by supervising the system’s timed operations and resetting it in case of a timeout.

The S-80144ALMC-JA5T2U is a small and reliable power management IC supervisor that provides a high degree of protection and accuracy. It can be used in a range of embedded and portable systems in a variety of industries, such as telecommunications, automotive, and consumer electronics. Its features, such as wide power supply range, power ON reset and enable features, accurate power ON detection, an independent watchdog timer, and an internal impedance matching network, make it highly efficient and precise. Its ability to sense any changes in supply voltage and current, as well as its constant temperature monitoring, make it the perfect choice for safety-critical applications.
