VN820-11-E Working Principles

The VN820-11-E is driven by a Pulse-Width Modulation signal, so that it can drive transistor switches, control their on and off times and control their output power. The driving circuit can be powered by a 9V battery or an external DC power source. The VN820-11-E has an output voltage of 3.5V and can control four power outputs at 5A each. Outputs 1, 2 and 3 can be used for linear power control and output 4 is for pulse-width modulation. The outputs are protected against over-current and short-circuit as well as thermal protection, preventing any damage to the IC.

The VN820-11-E is also equipped with sensors for monitoring the temperature, current, and voltage of the connected devices. This helps maintain the power levels when the connected devices pull high current. The device also monitors and store the power usage for each device for future reference.

The VN820-11-E is multi-source compatible, meaning it can process different power sources, both AC and DC, to ensure the stability and reliability of the power output. Furthermore, the CAN connectivity also allows for remote control using standard CAN controllers. The CAN interface has a receiver sensitivity of 96dB, so that it can transmit and receive data over long distances.

Conclusion

The VN820-11-E is a power management IC equipped with several features to ensure the safe, efficient and reliable flow of power distribution and control. Its use in applications such as automotive and industrial automation give it a wide deployment potential, allowing for more convenience and better control of power in connected devices.
