Isolators - Gate Drivers

Structured around a space-saving PowerDI 123 package, the SI8235AB-D-IMR isolator is an effective gate driver module that is great for switching applications, providing good electrical isolation between the inputs and the outputs. It is designed to drive most types of power MOSFETs, allowing signals to be transmitted through galvanic isolation to reduce noise and cross-talk.The SI8235AB-D-IMR isolator operates off a wide voltage range of 4.5 V (minimum) to 18 V (maximum) and it can deliver a maximum output current of 6A per output. The maximum propagation delay of 3 µs helps ensure a fast, accurate response time. It utilizes pulse transformers for signal isolation and offers up to 6500 Vrms isolation voltage. The module is cost-efficient due to its simple design and it uses low power consumption, making it a great choice for mobile applications.The primary application of the SI8235AB-D-IMR isolator is switching applications. It is especially useful in low-power and high-speed power MOSFET applications such as motor control, power inverter, thyristor inverter, switching power supplies, and loads.The SI8235AB-D-IMR isolator features surge protections and over-temperature protection that helps protect the device from potential damage in case of power surges or system overheating. This protection helps extend the life of the device and helps reduce downtime in applications.The operation of the SI8235AB-D-IMR isolator is simple, yet effective. The electrical isolation between its input and output is achieved by bridge-type transformers which couple together the two signal domains, allowing signals to be transferred through galvanic isolation with minimal cross-talk and interference. This helps ensure reliable power delivery to the connected load and affords a high level of protection to the connected equipment. The SI8235AB-D-IMR isolator is designed to be easy to use and install, and it requires minimal external components such as N-channel MOSFETs. The module also features an integrated gate driver which helps regulate the switching speed of the MOSFETs for improved efficiency. It also helps simplify the design of the associated control circuitry, simplifying wiring and reducing the number of components.Overall, the SI8235AB-D-IMR isolator is an excellent solution for applications that require reliable electrical isolation with minimal cross-talk and interference. Its simple design makes it easy to use, while its integrated gate driver and protection mechanisms help ensure long-term reliability. The device is also cost-efficient, making it an attractive choice for applications that require low-power, high-speed switching performance.
