NCP380LMU05AATBG is a member of the PMIC – Power Distribution Switches, Load Drivers family of products, providing power control and protection. NCP380LMU05AATBG can be used in a variety of applications and comes with a range of features and benefits.

Application Field

NCP380LMU05AATBG has a wide range of applications, making it suitable for use in multiple industries. It is designed for automotive, industrial, and telecommunication systems. It is suitable for use in applications that require a low-current 3-5V solution, such as resistor and capacitor networks, automotive power supplies, critical communication equipment, and power converters. It can also be used in data communication, medical, and IoT applications.

Working Principle

NCP380LMU05AATBG is designed for power distribution, load monitoring, and protection. The device contains an integrated low-side FET that helps reduce current consumption. This FET provides up to two A current capabilities and up to 2-3 minutes of over-voltage protection. It also has adjustable active low-side current limit settings (up to 150 mA) and adjustable PWRGOOD and power-fail outputs.

The FET is connected to a 3-5V logic and feedback control circuit. The logic circuit is used to control the FET, monitor the voltage level across the FET, and provide a reset signal for the over voltage and over-temperature protection. The feedback circuit is used to monitor the output voltage and provide a PWRGOOD signal when the output voltage is within a predetermined range.

The device also contains two overvoltage protection (OVP) features to protect against overcurrent in the load, such as a short circuit or excessive load. The OVP will shut off the power when the load exceeds the set current or voltage. Additionally, the device offers a thermal shutdown capability that will shut off the power if the temperature of the device exceeds a predetermined threshold.

Conclusion

The NCP380LMU05AATBG is a versatile PMIC designed for use in a variety of automotive and industrial applications. It provides power control, protection, and monitoring through an integrated FET and 3-5V logic and feedback control circuit. The device also contains over-voltage protection, adjustable current limit protection, and thermal shutdown capability. This makes NCP380LMU05AATBG an ideal solution for power distribution and load monitoring applications.
