The AON2290 is a versatile, single-channel, N-type Field Effect Transistor (FET) power switch. It offers an ideal solution for switching applications requiring low on-resistance, high performance in a compact, low-cost package. The AON2290 is an excellent choice for switching high-power, low-frequency dc and digital signals.The device is based on an advanced proprietary process to achieve an optimized layout for maximum performance and efficiency. It has high-performance on-resistance, with a typical value as low as 0.07 ohms. The on-resistance can be enhanced via its built-in variable-frequency current limiting function. Through this current limiting function, the switching time is adjustable to be as short as 2µs, while the maximum load current can be set to 20A.The AON2290 has integrated over-voltage protection, short circuit protection, and over-temperature protection features. This allows users to switch high-power signals in a safe and reliable manner. It also provides protection against short circuits and over-voltages, reducing the chance of system damage due to excessive power consumption or voltage stress.The operating voltage of the device is 2.7 V to 5.5 V. It also has a wide range of package options, compatible with both surface mount and through-hole designs. The device can be easily interconnected with other components, making it a great choice for prototyping and development.The AON2290 power switch operates using a single-channel Field Effect Transistor (FET), which utilizes drain-source voltage (Vds) to control the on/off states of the device. The device is designed such that when the voltage on the gate (Vgs) is below the threshold voltage (Vt), the FET is off. When the gate voltage is above the threshold voltage, the FET is in an on state. The drain-source voltage (Vds) is used to set the threshold voltage (Vtsub), and the gate-source voltage (Vgs) is used to control the channel current.The drain-source current is proportional to the gate voltage, and the gate voltage determines the “on” and “off” states of the FET. The drain-source current can be limited using the variable frequency current-limiting feature, allowing for controlling the desired power level. The device also has integrated protection diodes at the source, drain, and gate terminals to protect from over-voltage events.The AON2290 power switch is a versatile, high-performance device, and an ideal choice for a wide range of applications. It can be used in motor control, automotive electronics, power supplies, consumer appliances, lighting control, and many other applications. The device’s low on-resistance, high current capacity, and integrated protection features make it an excellent choice for switching high-power, low-frequency dc and digital signals.
