Working Principle

ISL6208CR is an advanced full-bridge gate driver which uses two-N-channel MOSFETs and output-level control. It utilizes a pair of N-channel MOSFETs that form a full-bridge with a DC input voltage. When the input voltage is turned on, the power switches and starts to charge a bootstrap capacitor. After the bootstrap capacitor is charged, the output voltage is applied to the gate drivers.

The output voltage level is controlled by varying the duty cycle of the output voltage. This allows for fast and soft switching edges, which helps to reduce EMI, increase efficiency, and improve power sharing capability.

The ISL6208CR can be used with a wide range of voltage ranges and frequencies. It is capable of switching frequencies from 200kHz to 5MHz, and can support both low application voltages (3.3V) and high application voltages (12V).
