Isolators - Gate Drivers

The SI8235BD-D-IS3 is a dual-channel isolator designed for driving gate circuits. This type of gate driver allows the gate to be connected electrically with low capacitive coupling, while at the same time providing a high voltage barrier between the driver and the gate. This provides electrical isolation for the gate driver, reducing the risk of electrical damage from spikes or electric arcs.

The SI8235BD-D-IS3 uses a photo-coupler to transmit gate signals between the driver and the gate. The photo-coupler consists of a pair of LEDs spaced closely enough together that light from one illuminates the other. When the LED on the transmitter side is powered, it triggers the LED on the receiver side, creating an electrical connection between the two.

The SI8235BD-D-IS3 is rated to drive a maximum voltage of 8V and is capable of handling currents up to 3 amps. It has a rise time of 0.04us and a fall time of 0.03us, making it suitable for use in high-speed gate drive applications. It also has a low power consumption of just 2.5 mW, making it ideal for battery-powered applications.

The SI8235BD-D-IS3 is an ideal solution for driving high-voltage gate circuits, as it provides electrical isolation while also offering fast switching speeds and low power consumption. It can be used in various applications, such as motor control, power supply converters, and digital logic systems, as well as in automotive and industrial applications.
