Isolators are invaluable in electrical systems, particularly those involving high voltages or temperatures. They provide a physical barrier between current-carrying electrical components, preventing direct transfers of energy or shocks between them. Gate Drivers are isolators specifically designed to control field-effect transistors like MOSFETS or IGBTs. These switches are used in many applications such as motor drives and inverters, and the ACPL-K312-060E is an example of a popularly used device.

The ACPL-K312-060E gate driver is a 16-pin package isolator used to drive a pair of N-channel MOSFETs. It provides a protection channel rating of 6000-V of average power and 3.75 kV for working voltage, ensuring that any voltage spikes from the source are blocked from impacting the FETs and other components in the system. It also provides one-direction current flow, so the current backflows from the load do not interfere with the circuit.

The ACPL-K312-060E functions by providing isolated channels for the control signals and power supplies. The device has two primary input channels for the control signal, which are usually driven by the microcontroller or logic gate. These signals are passed through the isolation barrier to the output side, where they are used to drive the gate of the respective MOSFETs. This isolated driven approach is essential for removing the risk of possible damages from the power circuit to the control circuit. Additionally, the ACPL-K312-060E provides a safety default mode where it automatically disables the FETs in case of an over-voltage or over-temperature condition.

The ACPL-K312-060E is specifically designed for mid-to-high-side PWM-based motor control applications. It can efficiently switch motor loads up to 100 Amps of continuous current, allowing it to be used for a wide range of systems. Its built-in integrated LED indicators and open drain fault signal can be used to detect circuit abnormalities or to monitor the working status of the device.

The ACPL-K312-060E is a highly efficient device, using only 2 mW of power, making it easily scalable for usage in battery-powered systems as well as in high power applications. Its low propagations delay time of 350 ns also ensures a high-speed response to the signals being passed through, allowing for a smooth operation of the system. This makes the ACPL-K312-060E an ideal solution for any motor control applications.
