Digital isolators play an important role in modern industrial electronics. They are used to connect separate circuits without any direct connection between them. They are designed for various applications, and the LTM2886HY-5I#PBF is an example of such application.

LTM2886HY-5I#PBF Application Field

The LTM2886HY-5I#PBF is a high voltage digital isolator, providing galvanic isolation between two circuits. It is designed to be used as an isolated gate driver, with a maximum switching voltage of up to 600 volts. It can be used as a digital isolator for opto-isolators, DC-DC converters, motor drives, and other industrial and medical applications.

Working Principle of LTM2886HY-5I#PBF

The working principle of the LTM2886HY-5I#PBF is based on the use of two identical power supply circuits, which are galvanically isolated from each other. The power supply circuit drives a pair of optically isolated N-channel MOSFETs, which provide galvanic isolation between the two circuits. The optically isolated MOSFETs can be controlled by providing logic level signals from a separate signal source. The logic level signals are amplified and latch up an MOSFET, which then generates its own pulse. The generated pulse then drives the other optically isolated MOSFET.

When there is a change in the logic level inputs for the MOSFETs, the change is propagated through the optically isolated MOSFETs and the other circuit is driven accordingly. Thus, the LTM2886HY-5I#PBF provides galvanic isolation of up to 600 V and a propagation delay of up to 20 ns. This makes it an ideal solution for applications that require maximum isolation and fast response time.
