2EDS8265HXUMA1 application field and working principle

The 2EDS8265HXUMA1,Also known as MARK³, is a gate driver from NXP semiconductor. It is an integrated gate driver that is used in a wide range of power management applications, such as solar, wind power, and lighting systems. Its internal bi-directional logic level shifter allows for level shifting on the high and low side of a gate drive, allowing it to drive both low voltage and high voltage circuits.

The 2EDS8265HXUMA1 consists of a gate driver and a gate driver controller, each of which is connected internally by an I2C-based serial data interface. The gate driver, also known as the MARK³, consists of a half-bridge power output, an overcurrent protection device, and a bi-directional logic shifter. The controller section handles the communication interface, and provides a control signalfor the gate driver logic level shifting.

The MARK³ is designed for high-side and low-side gate driving applications. The 2EDS8265HXUMA1 gate driver powers an external pair of MOSFETs, or IGBTs, that control the positive and negative path of the system. The IS-LIM and IS-SD pin can be connected to the MOSFETs or IGBTs in order to monitor their current level, and protect the system from any overcurrent situation.

One of the main features of the 2EDS8265HXUMA1 is its adjustable dead time. The adjustable dead time circuit allows the output to be changed by varying the voltage on the CTRL pin, which is connected to the controller section. This helps in preventing shoot-through of the MOSFETs or IGBTs, and ensures better protection against over current problems.

The 2EDS8265HXUMA1 also has an integrated temperature protection feature. By utilizing the controller\'s temperature sensing capabilities, this driver can detect either local or remote temperatures and immediately enter into a safe-state shutdown mode until the temperature is back to a safe level.

The 2EDS8265HXUMA1 is suitable for a variety of power management applications, including AC/DC power converters, DC/DC converters, LED lighting, automotive, and UPS systems. Its integrated safety protection features make it a dependable choice for anything requiring reliable gate driver protection.
