Skyworks Solutions Inc. Si82Ex Evaluation Kits
Skyworks Solutions Inc. Si82Ex Evaluation Kits are designed to evaluate and test the functionality and performance of the Si82Ex isolated gate drivers. The evaluation board can be used in standalone mode with an oscilloscope and the onboard dummy capacitive load, or it can be connected to a switch mode power supply (SMPS) controller and external power MOSFETs to conduct a system-level evaluation.
The Skyworks Si82Ex dual-channel isolated gate drivers feature variable current drive (VCD) and universal input in WB SOIC14 (6kVRMS isolation), NB SOIC16 (3.75kVRMS isolation), and LGA13 (2.5kVRMS isolation) packages.
In systems where the controller handles overlap protection and dead time control, the Si82Ex kit universal input attribute permits the chip to function as two independent drivers in any high-side + high-side, low-side + low-side, or high-side + low-side topologies.
The kits cover a wide variety of Si82Ex drivers. Nonetheless, depending on the driver IC on the board, some features are only available on specific boards.
Features
- VIA/VIB inputs or PWM input
- Dead time adjustment
- Input signal overlap protection
- Variable current drive (VCD) eliminates external gate resistors
- Universal input to support dual-driver operation
- 150kV/µs common mode transient immunity (CMTI) performance
- Reverse polarity protection
- Various power supply schemes support unipolar and bipolar gate output voltages
