ACPL-P347-560E is an isolated MOSFET/IGBT gate driver from Avago Technologies that can be used to drive small signal MOSFETs or IGBT modules with output current rating of up to 500mA. The ACPL-P347-560E isolator is a single-channel driver and has two input control signals that can be used to switch power MOSFETs or IGBTs with various topologies.

Application field

The ACPL-P347-560E isolator is suitable for applications in a wide variety of motor control systems, including industrial, power generation, automotive and aerospace applications. It is also well suited for applications where isolated power is required such as radio and television broadcast, cellular base stations, and medical electronics.

The ACPL-P347-560E isolator features fault condition detection on the input and output side of the optically isolated interface. This capability simplifies the circuit design process and allows the system designer to accurately detect and respond to errors in the device\'s operation.

Working principle

The ACPL-P347-560E isolator is based on small-signal optically coupled MOSFET drivers with integrated high-speed isolated voltage feedback signal. The voltage feedback signal isolates control signals from the circuit so that they can be used to control loads outside of the circuit without introducing errors in the load device or system.

The device has two integrated digital inputs, one used to turn the output MOSFET/IGBT on and the other to turn it off. The gate voltage can be adjusted by means of an external potentiometer and also by PWM signals. The device also includes provisions for overcurrent and overtemperature protection. It also has an internal shutdown circuit for protection against reverse voltages.

In addition, the ACPL-P347-560E isolator has a low ground current draw, making it ideal for energy-efficiency applications. The device also features short-circuit protection and a deadtime control mode that allow the system designer to optimize system performance.

The ACPL-P347-560E is an ideal solution for motor control applications where isolated power is required or when using high-speed switching topologies. The device is also suitable for applications that require very precise control and protection, such as medical electronics, broadcast and communication.
