SI8287BD-ISR Working Principle

The SI8287BD-ISR gate driver is designed to drive MOSFETs and IGBTs in high-frequency, high-power applications. It incorporates an advanced level shifter built from MOSFETs, allowing it to drive a logic-level signal up to 1.7kV with minimum power loss.

The driver includes over-temperature protection, adjustable dead time control, and adjustable current limitation. It will enable output of up to 12A, and high chopping frequency operation up to 250kHz with dv/dt immunity up to 10V/ns. This driver gives glitch-free switching between half-bridges, allowing for greater efficiency and higher speed operation.

Furthermore, the SI8287BD-ISR gate driver also includes an enable function, allowing the user to control the driver’s output and enable/disable the device. This can help to reduce power loss during idle periods, or when the device is not being used.

The SI8287BD-ISR is part of the gate-driver family of products from SGS. It can be used with a variety of MOSFETs and IGBTs with different voltage levels, making it suitable for motor drives, brushed DC motor control, welding inverters, and other power conversion applications.
