AON7902

The AON7902 is a logic-level enhancement-mode N-channel metal-oxide-semiconductor field-effect transistor (MOSFET) array. It is designed specifically for low voltage, high-current switching applications. This particular device is a 4-channel array, meaning it is capable of controlling up to four separate paths or circuits.

The AON7902 is a versatile device and is well suited for a variety of applications. It can be used as a driver for stepper motors, for audio amplification, for switching and controlling high-current loads, for power supplies and motor drivers, and more. Additionally, it can be used as an amplifier, switching regulator, variable-speed motor driver, etc. Because of its low voltage and high current capabilities, the AON7902 is ideal for battery powered applications.

The AON7902 works by using the principle of depletion mode FETs (field effect transistors). In a depletion mode FET, the applied voltage controls the flow of current through the device. When a voltage is applied to the gate, the current flow is blocked. This allows the device to act as a switch or amplifier, depending on the circuit application. The AON7902 has a threshold voltage of 1.25V, meaning that any voltage applied to the gate which is below this threshold will result in the FET being off, or not allowing current to flow through.

The AON7902 also has a variety of other features that make it ideal for applications requiring voltage and current control. It has a low input capacitance, meaning it can respond quickly to changes in the applied voltage. Additionally, it has a high breakdown voltage, meaning it can handle higher voltages without needing specialized components like zener diodes. Lastly, it has a wide operating temperature range, meaning it can be used in harsher environments.

In summary, the AON7902 is an excellent choice for applications requiring low voltage, high current control. It is versatile and the depletion mode FET design makes it ideal for a variety of applications, especially those where quick responses and high breakdown voltages are required. Additionally, its low input capacitance and wide operating temperature range make it well suited for many battery powered applications.
