IX4425NTR

The IX4425NTR is a P-Channel class Enhanced Leading-Edge Blanking (eLEB) MOSFET driver designed for consumer electronics, computer and communications systems, solar energy and other applications that require a low power driver IC. The IX4425NTR improves the efficiency of the turn-on operations of a MOSFET. It employs the eLEB architecture to reduce switching losses during turn-on and has a maximum output current of 200mA.

The IX4425NTR is specifically designed to operate in consumer electronics, computer and communications applications primarily powered by a battery voltage or any other low voltage regulation supplied power. It also allows efficient operation of the power switch at very low supply voltages, down to 0.8V.

The IX4425NTR is suitable for driving loads such as metals oxide semiconductor field effect transistors (MOSFETs), integrated circuits with MOSFET output, GaN power switches, and power half-bridges in various automation controller, home appliance, and consumer electronics applications. It is available in an 8-pin AgNi-Pd package.

Working Principle

The IX4425NTR uses a P-Channel MOSFET structure to achieve the best performance. It employs an eLEB architecture which allows the leading edge of each pulse to be blanked off, reducing switching energy losses by more than 50%. This reduces the turn-on delay and improves the switching performance and the overall efficiency of the system.

The IX4425NTR is designed to be used as a gate driver for a P-Channel MOSFET. The device has three inputs: a logic control input (GATE), a logic enable input (EN), and a logic reset input (RST). The logic enable and reset inputs control the power switch by turning off and resetting the circuit when not needed to save power.

The device is also equipped with a built-in current limit circuit. This allows a constant current to flow through the driver, regardless of voltage, thus providing high-level safety protection. The current limit is adjustable and can be set to the desired value.

Applications

The IX4425NTR is ideal for use in consumer electronics, computing, communication, and solar energy applications. It is suitable for use in systems where low-power drivers are needed and the switching speed is critical. Some applications include the the following:

• Home Appliances
• Automation Controllers
• Digital Power Supply Controllers
• Battery Powered Systems
• Data Center and Telecommunications
• Solar Panel Inverters
• Power Over Ethernet (PoE) Switches
• Bluetooth and Wi-Fi Access Points
• LED Lighting
• Wireless Chargers
