Working Principle

The working principle of the PX3516ADDGR4XTMA1 gate driver involves two integrated drivers with discrete power MOSFETs connected to each side of the full bridge. When the gate driver is driven by either the high side or the low side driver, the gate voltage of the connected MOSFET is rapidly switched from low to high, driving the MOSFET into an active conduction state. This high-speed switching is achieved by introducing a short period of pulse width modulation (PWM) when the high side and low side drivers are both switched on. This allows for high-speed, efficient switching of power MOSFETs.The device also features an internal current-limit control, that can be enabled when the current drawn by any of the switch channels exceeds its threshold. This is helpful in preventing over current conditions in the circuit by limiting the current and maintaining safe operating conditions. Additionally, the PX3516ADDGR4XTMA1 also features integrated over-current, over-temperature and over-voltage protection to ensure reliable operation. This means that in the event of a fault condition in the circuit, the device will automatically shut off to prevent further damage.
