The ACPL-W346-500E isolator is an integrated circuit that can work as a driver for gate drives in a variety of applications. This device\'s gate input accepts common drive signals (non-inverting) such as TTL, CMOS, and how signals, and its output can drive the gate of a power switch with an opto-coupler or equivalent isolation device. As an isolator, It prevents high voltages, currents, and power switching circuits from influencing the control circuitry on the low-voltage side.

Overview of the Application Field

The ACPL-W346-500E provides an isolator interface for gate drives in applications such as motor drives, controllable reactors, and motor control systems. It can provide isolation for both 2.5amp (24V) and 8amp (60V) circuit level power switches. The device has current limit protection up to 4A for the output stage, and can be easily implemented across a wide range of applications.

Operation Principles

The ACPL-W346-500E isolator has two primary components- a high-side gate drive opto-coupler, and a low-side logic driver. The high-side gate drive opto-coupler isolates the low-voltage control circuitry from the high-voltage power switch drive. This device consists of a light emitting diode (LED) and an optically coupled phototransistor pair, which is used to electrically separate the control circuitry from the gate driver circuit. The LED is driven by the output of the low-side logic driver, which provides the gate driver output of the ACPL-W346-500E.The low-side logic driver accepts common drive signals such as TTL, CMOS, and how signals, and converts them into the output current required by the high-side gate drive. The low-side logic driver has a power supply range of 5.5V to 24V and is able to operate between -40°C and +85°C.

Conclusion

The ACPL-W346-500E isolator provides a simple, cost effective solution for driving gate drives in applications such as motor drives, controllable reactors, and motor control systems. Its two main components- the high-side gate drive opto-coupler and the low-side logic driver- provide insulation as well as the necessary output current. In addition, the device has current limit protection up to 4A for the output stage, making it a reliable driver for gate drives.
