PMIC – Supervisors: NCP301LSN12T1 Application Field and Working Principle

PMIC supervisors are integrated circuits (ICs) that are used to protect electronic systems from overvoltage and overcurrent conditions. They are available in many forms, such as linear, linear-switching, and pulse-width-modulated (PWM) designs. The NCP301LSN12T1 is a linear-switching PMIC supervisor with the capability to detect an open-drain output. This type of supervisor is commonly used in modern power management systems.The NCP301LSN12T1 is designed to provide a simple, low-cost solution for power-management applications requiring wide input voltages and a wide range of system monitoring options. It offers a host of features such as a low supply current of 50μA, an operating voltage range of 1.2V to 5.5V, and overvoltage and overcurrent protection. The NCP301LSN12T1 is specifically designed for temperature-sensitive load-switch applications, such as distributed and battery-powered systems. It features an open-drain output to turn on the power switch when an overvoltage or overcurrent condition is detected.The NCP301LSN12T1 provides a signal for an external power switch when an overvoltage or overcurrent condition is detected. The device detects an overcurrent condition when the supply current exceeds a programmable threshold. The device is also capable of detecting an overvoltage condition by comparing an internally generated voltage threshold with an external voltage input. The device can be configured to assert a reset or interrupt signal when either of these conditions is detected. The NCP301LSN12T1 can also enable a built-in safe-start feature that reduces the supply current below a maximum current until a valid supply is available.The NCP301LSN12T1 can also be used to detect supply-voltage and system temperature. The device can be configured to assess the temperature of a component on the system by monitoring the voltage at an external temperature-sensor terminal. It is also capable of monitoring the input supply voltage, which makes it ideal for systems utilizing distributed, cellular, and variable-power sources.The NCP301LSN12T1 is a robust solution for power-management applications such as switching power supplies, intelligent routers, and portable media players. It is also capable of integrating a wide variety of voltage and current-monitoring functions. This makes it a versatile choice for applications that require power-management solutions that are both cost-effective and reliable. In conclusion, the NCP301LSN12T1 is a reliable and cost effective solution for power-management applications that require wide input voltage ranges, overvoltage and overcurrent protection, and temperature monitoring. It is a versatile device capable of integrating a range of voltage and current-monitoring functions and is suitable for a variety of applications.
