BP818
Magnetic Coupler Isolator
Description
The BP818 is a magnetically coupled isolator designed for communication between primary and secondary of offline power supplies. The BP818 has two built-in coupling coils and utilizes the
magnetic coupling to communicate information, while
providing galvanic isolation. The BP818 offers stable and reliable performance eliminating the disadvantages of traditional optocouplers such as low precision and nonlinear current transfer ratio, as well as limited lifetime. The BP818 operates without bias current on both the primary and secondary sides, which greatly reduces the system standby power consumption.
