Introduction
The S-80950CLNB-G7LT2G is a Supervisors PMIC (power management IC) designed to provide power control and system monitoring functions in a wide range of applications. In particular, it is well-suited for use in automotive, industrial, and consumer products. The device integrates multiple programmable regulators, power inputs, outputs, and advanced monitoring and protection features into a single low-power, low-profile package. It also offers a range of features, such as adjustable trip points, multiple reset/holdoff options, adjustable output current, and diagnostic outputs for improved system reliability.Application Field
The S-80950CLNB-G7LT2G is designed for use in automotive, industrial, and consumer applications. It can be used to monitor and control power distribution, battery charging systems, and other power management systems. It is also well-suited for use in automotive, industrial, and consumer products, including on-board diagnostic systems, precision equipment, industrial motor control, and motor starters. The device is especially well-suited for use in automotive telematics, remote auto engines, and cabin control systems.Working Principle
The S-80950CLNB-G7LT2G integrates two programmable regulators to deliver adjustable output voltage and current to various on-board circuits. This includes a main regulator, which can be programmed to provide continuous output current up to 1.5A and adjustable output voltage of 0.6V to 3.3V, as well as a dedicated line regulator, which can provide an output voltage up to 5V. Both regulators are well-suited for low-noise power management applications.The device also provides two power inputs and three outputs, which can be programmed for a variety of system monitoring and protection functions. The first power input (input 1) is intended for use with a primary power source, such as a battery or power supply. Input 1 can be configured to work with either constant voltage or constant current sources or a combination of both. The second power input (input 2) is intended for use with an auxiliary source, such as a backup power supply.The device also includes three diagnostic outputs, which can be configured to indicate system status, such as power up, power down, input over voltage, under voltage, or short circuit. The diagnostic outputs can be programmed to generate reset signals, delay reset signals, or monitor power supply voltage.The device also includes a watchdog timer, which can be used to reset the system if a specific event occurs or to restart the system after a predetermined amount of time. The watchdog timer can also be used to periodically interrupt the system for testing purposes or for system monitoring.Finally, the device includes a Brown-out reset (BOR) feature, which can be used to generate a reset signal if the system voltage drops below a set threshold. The BOR feature can also be used to indicate system power-up or power-down status, as well as low-battery conditions.Conclusion
The S-80950CLNB-G7LT2G is a PMIC - Supervisors suitable for use in automotive, industrial, and consumer applications which combines reliable power management and monitoring features into a single low-power, low-profile package. It integrates two programmable regulators, two power inputs, three outputs, two diagnostic outputs, a watchdog timer, and a Brown-out reset feature, which can all be used to monitor and control power, detect faults in the system, and provide a reset signal for system reboot.
