AO4726 is a densely integrated high-density CMOS device that combines four independent N-channel power MOSFETs with the power switch within a single integrated circuit. It is designed for applications with high drain-source voltage and resilient blocking capability. This article focuses on discussing the application field and working principle of AO4726.

Application Field of AO4726

AO4726 can be applied in a wide range of fields due to its high drain-source voltage and resilient blocking capability. Generally, AO4726 can be used as automotive electrification and portable equipment. In the field of automotive electrification, it is mainly used as control elements in power stages and on-board circuitry, such as motor control, low-side switches, battery switches and controllers. In the field of portable equipment, AO4726 can be used to build efficient auxiliary power supplies, charger controllers and dynamic battery management systems.

AO4726 can also be used in a variety of industrial applications. In industrial automation, it can be used as power switches, load switches, level shifter, motor control, and lamp control. In renewable energy systems, it is suitable for high voltage control, like solar panel inverters, grid tie inverters, DC-DC convertors, and wind power equipment.

In other applications, AO4726 can be used as a power switch for high voltage demoboard, a power switch for industrial equipment, a power regulator and an electronic switch of advanced and complex electronic systems.

Working Principle and Features of AO4726

The heart of AO4726 is a four channel, N-channel MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) array, which is used as a power switch. It is powered by a single supply voltage between 3V to 24V and can switch high-current and high-voltage signals. The operating voltage range is from -12V to 110V and the maximum drain-source voltage is 110V/275V. The RDS (on) value is as low as 11.3mohm/square. The MOSFET array also has a superb diode with fast body diode recovery time and low voltage operation.

The most outstanding feature of AO4726 is the short circuit protection, which ensures that the current flowing between node and Node N+ is not exceeding the maximum level of the device and the current won’t damage the device due to prolonged overload conditions. Moreover, its power supply rejection, thermal protection and temperature resistance features also give it a wide range of applications in harsh environment.

In addition, AO4726 also has a convenient sleep/wake mode, which allows automatic sleep/wake capability under different over-voltage/under-voltage conditions, which makes it suitable for power-sensitive applications. It is also able to reduce the switching frequency to lower heat dissipation and maintain high efficiency.

Conclusion

AO4726 is a densely integrated high-density CMOS device with the power switch included in a single integrated circuit. It is designed for applications with high drain-source voltage and resilient blocking capability. Its application field can be used for automotive electrification, portable equipment and industrial applications. Its working principle and features also make it suitable for different kinds of applications, such as short circuit protection, sleep/wake mode, thermal protection and temperature resistance.
