The L9820D013TR is a power distribution switch and load driver manufactured by STMicroelectronics. It is a controller-based power distribution switch that is designed to provide power supply, conditioning and fuse protection. The device is capable of handling up to 3A in a 1-channel configuration and up to 6A in a dual-channel configuration. It is optimized for cost-sensitive applications and provides a highly integrated solution for controlling loads in an energy efficient manner.

The device uses a bi-level supply voltage to realize the power distribution switch and load drivers. The levels of the power source voltage, VCC and GND, are chosen based on the load, switching requirements and power dissipation. The switching speed of the device is adjustable through the internal voltage regulator and it can deliver up to 6A while operating in a conventional duty cycle.

The L9820D013TR incorporates a bridge rectifier and a power FET to deliver the required voltage to the load. It also has current limit protection and over-temperature detection to ensure the safety of the system. A digital micro-controller is included in the device to properly manage the power distribution and load sharing. The micro-controller is capable of managing up to 16 loads in a 1-channel configuration and up to 32 loads in a dual-channel configuration. The micro-controller also includes a power saving mode to reduce the power consumption when the device is idle.

Furthermore, the L9820D013TR incorporates programmable current limit and over-temperature protection with adjustable current thresholds. The device also includes an important feature called “fuse mode protection” to provide additional protection from over-temperature and overload conditions. This feature is useful for applications that require optimal protection from over-temperature and overload conditions.

Finally, the L9820D013TR is extremely small in size and thus is ideal for portable applications. It is certified by the EU RoHS and manufactured according to the IEC 60619 standard. It also comes with a comprehensive FPGA-friendly API and some diagnostic and power monitoring functionality.

In conclusion, the L9820D013TR is an ideal solution for power distribution switch and load driver applications. It is a highly integrated controller-based solution that combines high performance, low cost and low power dissipation with a small form factor. With its optimized design, it offers an efficient and cost-effective option for controlling loads in a wide range of applications.
