PMIC Supervisors are some of the most important control and protection components used in systems to enhance reliability, maintain performance stability and achieve optimal power savings. The S-80149CLPF-JJATFU is an innovative supervisor that provides highly effective current-limiting protection from short circuits or inrush current when used in electronic systems.

The S-80149CLPF-JJATFU is an advanced PMIC supervisor targeted specifically for microcontrollers and DC/DC converters used in various applications. The device offers both thermal and current protection, simplifying the design process and reducing cost. It features an adjustable reset threshold up to +125°C and a delay up to 1 second. Additionally, the device has a built-in electrical current limiting protection.

The applications of the S-80149CLPF-JJATFU include a wide variety of microcontrollers, automotive and white goods applications. Due to its improved current-limiting performance and higher over-temperature threshold, the supervisor can operate in very challenging high power environments. In addition, it can provide superior thermal and current protection for systems with high-speed switching power supplies.

The S-80149CLPF-JJATFU is designed to provide reliable operation under extreme temperature, humidity and power conditions. The supervisor is powered from a wide range of voltages, from 2.0 V to 4.5 V. An internal circuit senses the input voltage and adjusts the reset threshold accordingly. The supervisor also features an active reset output and open-drain output.

The working principle of the S-80149CLPF-JJATFU is simple. The device monitors an input voltage and an external resistor sets the reset threshold. When the device is enabled, the voltage at the input pin is compared with the reset threshold. If the voltage exceeds the threshold, the supervisor generates an active reset signal and the user’s system is immediately reset. Additionally, if the temperature rises above the chosen threshold, the device will maintain a low reset signal, until the temperature drops within the acceptable range.

The device also features a built-in current sensing circuit, which will detect excessive current levels and protect the user’s system from damage. The current limit is adjustable via an external resistor, allowing the user to set the maximum current level. If the current exceeds this threshold, the off-state output will remain low until the current drops to a safe level. This prevents damage to the user’s system, as well as ensuring maximum power savings.

The S-80149CLPF-JJATFU is a powerful PMIC supervisor solution for microcontrollers, DC/DC converters and other high power applications. With an adjustable reset and current limit, the device provides superior protection, ensuring safe and reliable system operation. The device also allows the user to monitor temperature, humidity and other environmental parameters, allowing for complete system control. The device is flexible, easy to configure and highly reliable, making it ideal for a wide range of applications.
