Solid State Relays

The AQH2213 is a two-channel digital switching integrated circuit designed for use as a solid state relay. It is commonly used in applications such as power switching and motor control. This IC contains two N-Channel MOSFET transistors that can operate in both digital and analog mode, providing flexibility for a variety of applications.

AQH2213 Application Field and Working Principle

The AQH2213 is suitable for use in many different applications, including HVAC, lighting, and industrial applications. The main feature of the AQH2213 is its ability to switch large currents with a relatively low power supply voltage. In addition, the device has voltage and current sense switching capability, allowing it to be used in applications such as motor control.

The working principle of the AQH2213 is based on the fact that the MOSFET transistors in the device can be switched between ON and OFF states in response to a control signal. When a logic high is applied to the gate of the MOSFET transistor, its source-drain junction is turned on and current can flow through the circuit. Conversely, when a logic low is applied to the gate, the source-drain junction is turned off and no current is allowed to flow. This makes the AQH2213 suitable for use in various switching applications.

The AQH2213 can also be used in analog applications by using its current sense circuit. This circuit provides feedback to the AQH2213, allowing it to switch the output at specific current settings. The AQH2213 has many advantages over conventional electromechanical relays, including reduced power consumption, increased reliability, and increased switching speed. These advantages make the device an ideal choice for switching applications.

The AQH2213 is a versatile device that can be used in a wide variety of applications. It is typically used for switching large currents in HVAC, lighting, and industrial applications. Additionally, it can be used for motor control and other applications where analog control is required. The AQH2213\'s features make it an attractive choice for most switching applications.
