Working Principle

The ADP3623ARDZ-RL gate driver\'s main function is to control MOSFET/IGBT/GTO power devices by generating a gate voltage proportional to the voltage on the source or drain of the power device. This gate voltage is used to forward-bias the power device\'s gate, which in turn activates the power device. The ADP3623ARDZ-RL utilizes a single power supply voltage and typically requires only one gate capacitor for optimum operation.The onboard driver offers a series of controls and safeguards that can prevent overheating by limiting inrush current, reducing propagation delays, and providing short circuit protection. The driver circuit also provides soft start functionality which can help reduce inrush current, and offers safety functionality such as over-temperature protection. It is also possible to adjust the turn-on and turn-off drive current, the switching frequency and the logic thresholds.

Conclusion

The ADP3623ARDZ-RL is a very effective PMIC gate driver for powering MOSFET/IGBT/GTO power devices in different applications. With its low on-resistance and fast switching capability, it makes an ideal choice for applications that need high system efficiency. The driver circuit provides several safety features, such as inrush current limiting, over-temperature protection, and soft start capability. It is also possible to adjust the turn-on and turn-off drive current, the switching frequency and the logic thresholds. This makes the ADP3623ARDZ-RL a more effective, robust and reliable PMIC gate driver for powering power devices.
