Isolators, also known as optoisolators, are used to electrically isolate two signals in a system. Gate drivers are used to control and drive high-current/high-voltage devices such as power transistors, power MOSFETs, and IGBTs. The SI8235BB-C-IS1 is an isolator-gate driver combination device suitable for applications in both communications and industrial automation.The SI8235BB-C-IS1 device contains two independent gate drive channels with an additional isolated supply input. The design also incorporates an integrated output stage, allowing the device to confidently switch voltage and current loads of up to 2A/400V. This makes the SI8235BB-C-IS1 a suitable solution for motor control applications.In communications applications, the SI8235BB-C-IS1 isolator-gate driver combination device can be used for high-speed, low-voltage systems. It provides isolation for the logic signals and helps protect the communication line from surges and spikes. Additionally, the built-in return-to-zero output feature makes it suitable for pulse-width modulation (PWM) applications.The SI8235BB-C-IS1 device utilizes a novel media isolation technology that eliminates the need for a magnetic field. This means that the device is able to maintain isolation even when applied current is high, making it more reliable than traditional isolator-gate driver devices. Additionally, the device consumes low power, making it suitable for battery operated applications.The working principle of the SI8235BB-C-IS1 isolator-gate driver combines a linear optocoupler, an LED-photodiode (optical) pair, and a MOSFET-based output stage. The LED-photodiode pair provides high-speed digital signal transmission across the isolation barrier with data transfer rates up to 200Kbps. The output stage consists of an N-channel output transistor that acts as an inverter, allowing the device to drive the external load.The SI8235BB-C-IS1 isolator-gate driver combination device is a suitable solution for applications in communications, industrial automation, and motor control. The media isolation technology eliminates the need for a magnetic field while providing isolation between the logic signal and the communication line. Additionally, its built-in return-to-zero output feature and low power consumption make the device suitable for pulse-width modulation (PWM) applications. This makes the SI8235BB-C-IS1 an ideal choice for longer lifetime and reliable performance in demanding applications.
