BD48K38G-TL

PMIC (Power Management Integrated Circuits) supervisors, also known as system management controllers, are devices that supply power and management abilities to an electronic system. The BD48K38G-TL is an ideal PMIC supervisor device for a wide range of applications, providing flexibility, power saving, and management in a low power, low profile surface mountable IC.

PMIC supervisors monitor supply and power rails, provide power management signals to the system under different conditions, and condition critical event signals from the system. BD48K38G-TL provides a comprehensive set of power monitoring and system control functions, including power sequencing, power fail detection, power-on reset, system reset, and watchdog. Its power monitoring capabilities can detect any voltage or current drops, overvoltage trips, and battery low voltages. It also allows for multiple power sequencing, reset inrush control, power-on reset, system reset, and watchdog timeout. All of its features are highly Programmable and customizable to the exact needs of the application.

BD48K38G-TL is designed to provide comprehensive power monitoring and system control solutions for a wide range of industrial, automotive, and consumer applications, including lighting and HVAC systems, power converters, power supplies, and embedded system controllers.

The BD48K38G-TL works by monitoring the voltage and current levels of the power rails. If any voltage or current drops, an interrupt signal is generated which is forwarded to the system\'s microcontroller (MCU) for further processing. This allows for intelligent power management and system protection, and provides a proactive mechanism for responding quickly to out-of-spec power changes. Its programmable power supervision pins can trigger power fail detection and power sequence events as well.

The BD48K38G-TL can also monitor the status of the system\'s power supplies, including AC or DC, and decouple and ground them as needed. Its integrated thermal protection provides safety against overheating in power-critical designs. Its fast and efficient programmable low-voltage detection (LVD) quickly detects any voltage drops in the power rails, avoiding power-related issues.

The device also features a configurable system reset to ensure that the system is properly brought up after a power-down event. The reset can be configured to either reset the entire system or only certain parts of the system. The integrated watchdog timer can also be used to reset the system in case of failure or unauthorized usage.

In addition, the BD48K38G-TL also provides a wide range of protection features. Its protection against overvoltage, undervoltage, overtemperature, and overcurrent can protect critical components from damage. It can also detect over-voltage events and accurately reset the system if the failure event is detected.

The BD48K38G-TL provides a comprehensive and reliable power monitoring and system control solution for a wide range of applications. Its advanced power management and protection features enable sophisticated systems to accurately monitor and manage power usage and protect critical components from damage due to out-of-spec power changes. Its highly programmable power monitoring and protection features can be customized to the exact needs of the application, providing flexibility and reliability to system designers.
