CHL8328-10CRT Application Field and Working Principle

PMIC – Voltage Regulators – Special PurposeThe CHL8328-10CRT (hereinafter referred to as CRT) is an integrated circuit primarily designed to monitor and control LAN (Local Area Network) power and voltage in various settings and applications. CRT is a specialized, external regulator of and applicable to all LAN devices classified in accordance to standards such as IEEE 802.3, IEEE 802.12, and EIA/TIA-568. It is also suitable for DC/DC converters and other power applications.CRT was developed by OKI Electric Industry Co., Ltd. and is ideal for managing LAN power requirements under diverse conditions and applications. This small unit can support output voltage currents up to 20A, temperature range between 0 and 85 degrees Celsius, operating temperature range between -30 to 120 degrees Celsius, and overvoltage protection of OVP up to 23V. It also has a wide range of characteristics that make it a versatile and effective tool in power management.In terms of power management, the CRT’s most critical feature is its ability to function both as a voltage regulator and a shutoff device. When used as a voltage regulator, the CRT constantly monitors the output voltage of the connected device and adjusts the necessary conditions in order to maintain the desired output voltage. This makes it particularly suitable for monitoring and controlling LAN power in settings where voltage fluctuations and surges can occur. The CRT can also be used as a shutoff device in order to prevent overvoltage or high current from damaging or destabilizing the connected device. It can detect overvoltage conditions and disconnect the power supply immediately, thus saving the device from potential damages. It also has the ability to detect over-currents, so when a certain maximum current threshold is exceeded, the CRT will shut off the power supply in order to prevent the device from further damage.In terms of other features, the CRT also contains several useful circuits that make it versatile and reliable. These include an input voltage detector, an output voltage lock circuit, an output voltage increase/decrease control circuit, an output voltage adjustment circuit, an auto-reset circuit, a soft-start control circuit, and a low-current detection circuit. All these circuits work together to provide excellent power management performance and stability.In conclusion, the CHL8328-10CRT is a very useful and versatile integrated circuit for power management. Its multiple capabilities make it an excellent choice for many LAN applications that require reliable and consistent power supply. Its ability to monitor and control output voltage, detect overvoltage conditions, and adjust for temperature changes make it a reliable and effective component for any power management system.
