AOZ1320DI-02 application field and working principle

AOZ1320DI-02 is a twin MOSFET with high efficiency load driver, which is a monolithic integrated power device made by Alpha and Omega semiconductor. It is mainly used to drive the MOSFET and IGBT switches in the power distribution systems and switching power supplies. This device is capable of providing fast switching speed high efficiency and long-term reliability through the control of gate capacitance and gate resistance.

This power device is specially designed to drive the power MOSFETs and IGBT switches in power distribution systems, switching power supplies and switch-mode converters. The device has a maximum output current of 20mA and a gate controlled voltage that can reach 18V.

Principles of Operation

The AOZ1320DI-02 consists of two N-Channel MOSFETs connected in parallel and the gate signals of both are connected to a single control terminal. The switching time of the MOSFETs can be controlled by controlling the gate resistors and the gate capacitors. The size of the MOSFETs can also be adjusted by adjusting the gate capacitors.

When the control terminal receives a logic high signal, the source to source resistance is reduced, allowing the MOSFETs to be driven faster. The MOSFETs are then able to reach their peak current carrying capacity faster, thereby enabling faster switching. When the control terminal is driven by a logic low signal, the source to source resistance is increased, thus extending the switching time of the MOSFETs.

The AOZ1320DI-02 also features a high-speed Pulse-Width Modulation (PWM) circuit, which is used for high-speed switching. This circuit is designed to minimize switching losses and improve the overall efficiency of the device. It also helps to reduce EMI emissions.

Applications

The AOZ1320DI-02 is capable of providing fast switching speed, high efficiency and long-term reliability in a wide range of power distribution and switching power supply applications. It can be used in devices such as switch-mode power supplies, high-power servo drives, motor control systems, HVAC systems, power distribution systems, and motor control systems. These devices can be used in automotive, industrial, communications, computer, and home appliance applications.

In conclusion, the AOZ1320DI-02 is a high-efficiency load driver that is specifically designed to drive the MOSFET and IGBT switches in power distribution systems and switching power supplies. It is capable of providing fast switching speed, high efficiency, and reliability thanks to its PWM circuit and adjustable gate resistors and gate capacitors. This device can be used in a wide range of applications, including automotive, industrial, communications, computer, and home appliance applications.
