Isolators - Gate Drivers provide galvanic isolation to motor control systems. They generally fall into two categories: Galvanic Isolation for Safety and Galvanic Isolation for Efficiency. The ACPL-W343-060E is an example of the Galvanic Isolation for Efficiency type as it helps reduce system costs and noise. The ACPL-W343-060E Gate Driver is an optically isolated high performance Gate drive optocoupler. It has an output current of 60mA and can easily handle up to 4A load current.

The ACPL-W343-060E Gate Driver has a wide operating range of 6V to 28V and comes with built-in noise suppression of >50V/ns with peak current up to 500mA. It is offered in a small SO20 package and provides isolation voltage of up to 2.5KVrms. The ACPL-W343-060E Gate Driver offers a fast rise time of < 0.5µs from 50% to 90% full scale allowing for high speed switching and is designed for automotive engine control applications.

The ACPL-W343-060E Gate Driver works by driving a MOSFET or IGBT from a control input as an opto-coupled device. The ACPL-W343-060E Gate Driver consists of two parts: the input phototransistor and the output MOSFET. The input phototransistor detects the input signal and converts it into an electrical output. This output drives the output MOSFET which in turn controls the gate voltage of the load device. In this way, the ACPL-W343-060E is able to provide fast, precise and reliable control of the load device.

The ACPL-W343-060E Gate Driver also has built-in emitter protection and built-in undervoltage lockout features that help to ensure reliable performance in a variety of applications. The emitter current limit helps to protect the optocoupler from excessive power dissipation while the built-in undervoltage lockout prevents operation when the input voltage is too low. Additionally, the ACPL-W343-060E Gate Driver features thermal shutdown so as to prevent the optocoupler from being damaged due to excessive temperatures. The IRIS-05 function processor also provides additional protection for the ACPL-W343-060E Gate Driver when used in harsh automotive environments.

The ACPL-W343-060E Gate Driver is a high performance, cost effective isolator suitable for a variety of applications. It is used in high speed MOSFET and IGBT switching applications in motor and automotive control systems. It can also be used as an input isolator for digital Isolator applications, providing galvanic isolation from a 3.3V or 5V supply.

The ACPL-W343-060E Gate Driver is a cost effective and reliable solution for motor control applications where efficiency and noise suppression are of the utmost importance. It is capable of providing up to 4A load current at a wide operating range of 6V to 28V. Its fast rise time of < 0.5µs also allows for high speed switching and its emitter protection, undervoltage lockout and thermal shutdown features offer the reliability and safety needed in many demanding applications.
