LTC2851CS8#PBF is an interface driver with 8-channel charge pumps for RS-485/RS-422 and isolated CAN transceivers. It combines dual 2:1 multiplexed charge pumps and a differential charge pump for transmitting and receiving data. The driver also features convenient microcontroller independent Tx/Rx integrated I2C-bus control and configurability.

The LTC2851CS8#PBF has a wide range of applications in industry such as industrial automation, medical and laboratory equipment, robotics, instrumentation, and even commercial and home applications. In particular, it is well suited for providing the necessary voltage levels for systems using an RS-485 or RS-422 interface. Furthermore, its ability to provide full isolation between power and data signals makes it an excellent choice to minimize noise and interference in automotive, industrial, and consumer applications.

The typical operating principle of the LTC2851CS8#PBF is to generate a steady output voltage level by using its dual 2:1 multiplexed charge pumps. The multiplexed charge pumps are used to charge up the node capacitance of each output, thus stabilizing the output voltage level. The differential charge pump is then used to produce a differential voltage between the two output terminals. This differential voltage is used to drive the RS-485/RS-422 bus.

In addition, the LTC2851CS8#PBF also provides I2C-bus interface for configurability. With this interface, the user can select desired operating parameters such as the output voltage levels, slew rates, and port direction. These settings allow for optimizing the driver performance for specific applications.

In summary, the LTC2851CS8#PBF is an 8-channel interface driver with dual 2:1 multiplexed charge pumps and a differential charge pump for RS-485/RS-422 and isolated CAN transceivers. It has a wide range of applications and is suitable for use in automotive, industrial, and consumer applications. It also offers I2C-bus interface for configurability, making it easy to customize the driver for your specific application needs.
