Product Information

Back to top
The Si8285 is isolated, high current gate driver with integrated system safety and feedback function. The device is ideal for driving power MOSFETs and IGBTs used in a wide variety of inverter and motor control applications. The Si8285 isolated gate driver utilizes Silicon Labs' proprietary silicon isolation technology, supporting up to 5.0 kVrms withstand voltage per UL1577. This technology enables higher-performance, reduced variation with temperature and age, tighter part-to-part matching, and superior common-mode rejection compared to other isolated gate driver technologies.

The input to the device is a complementary digital input that can be utilized in several configurations. The input side of the isolation also has several control and feedback digital signals. The controller to the device receives information about the driver side power state (Si8285) and fault state of the device and recovers the device from fault through an active-low reset pin.

On the output side, the Si8285 provides separate pull-up and pull-down pins for the gate. The Si8286 has a single pin for both functions. A dedicated DSAT pin detects the desaturation condition and immediately shuts down the driver in a controlled manner. The Si8285 device also integrates a Miller clamp to facilitate a strong turn-off of the power switch.

Automotive Grade is available for certain part numbers. These products are built using automotive-specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
