Power management integrated circuits (PMICs) are an important component of many different electronics applications, providing control and monitoring of power inputs and outputs. PMICs can have a variety of different applications, from basic voltage regulation to complex controller management tasks. One type of PMIC is a supervisor, which is a specialized monitoring circuit that can detect and respond to specific conditions, such as power supply failure or overcurrent. The LP3470M5-3.65/NOPB is a Lo-Side supervisor from Texas Instruments (TI). This application note will discuss this device\'s application field, its working principle and the associated power management features.

The LP3470M5-3.65/NOPB is designed to supervise multiple power rails in various power management applications. It helps to ensure that system power is maintained and any unexpected supply voltage drift or fault is quickly detected and properly reported or responded to. The supervisor is also capable of monitoring various parameters, including voltage, current and thermal information. This allows it to make decisions and respond in a timely manner, ensuring the system\'s power stays within the intended limits.

As far as the application field of this supervisor goes, the LP3470M5-3.65/NOPB is ideal for use in laptop, notebook, tablet and other mobile device applications. The device is small in size and can be easily incorporated into a PCB design without taking up too much space. It is also capable of detecting and responding to a wide range of input voltages (2.2V up to 8.9V DC) and temperature values (0°C up to +90°C). These features make it suitable for a variety of power management applications, including system reset and power-on sequencing, hot-swappable system control, system thermal protection and overvoltage protection.

The LP3470M5-3.65/NOPB\'s working principle is based on the principle of threshold protection. When the supply voltage drops below or rises above the programmed threshold value, the supervisor will trigger an onboard reset or fault signal. This signal can be used to reset the system or trigger an alert response, depending on the system\'s particular application requirements. The LP3470M5-3.65/NOPB implements a wide range of thresholds and response parameters which can be programmed using an external voltage control input.

The LP3470M5-3.65/NOPB supervisor also provides a range of other related features that can help with power management. It features a power-on reset delay, which can be used to ensure that the system is given enough time to properly power up before the supervisor begins monitoring input voltages. Additionally, the supervisor can also detect current leakage, short circuit and under-voltage conditions and respond accordingly.

Overall, the LP3470M5-3.65/NOPB is a compact, feature-rich Lo-Side supervisor which is well-suited for application in laptops and other mobile devices. Its design is based on the principle of threshold protection and includes a range of power management features, such as thermal protection and current detection. With its wide range of input voltage and temperature thresholds, the supervisor is capable of reliably supervising a variety of different power rails, replacing the need for additional reset controllers or sequencers.
