RT9728AHGE Application Field and Working Principle

RT9728AHGE is classified as PMIC - Power Distribution Switches, Load Drivers. It is a high-side and low-side power switch for use in a broad range of power distribution applications. It is an ideal replacement for a Mechanical Relay or a FET, offering up to 30V VMAX and up to 3A of current from a single IC.

Application Field of RT9728AHGE

RT9728AHGE can be used in numerous applications, such as controlling pumps, motors, LEDs, amplifiers, and any other device that requires control of high-current or high-voltage devices. It is also suitable for Smart Home applications or any other application that requires a high level of Current and Voltage Control.

Working Principle of RT9728AHGE

RT9728AHGE has an input pin that controls the current flow. When the input is high, the Internal transistor is switched on, resulting in parallel-connection of the high-side and low-side switches. The RT9728AHGE has two sets of EN and Pins, one for the high-side control, and one for the low-side control. When the EN pins are low, the corresponding switched is turned off, and the other switch will turn on. This allows for selective control of the high-side and low-side devices.

In addition, RT9728AHGE has an integrated internal over-voltage protection. This feature protects both the high/low sides from being exposed to excessive voltages. This is essential when using devices such as motors or gasoline engines, which can cause excessive voltage spikes. RT9728AHGE is also protected from reverse currents, protecting the high/low sides from potential damage.

Conclusion:

RT9728AHGE is an ideal choice for high-current and high-voltage applications. It is suited to a wide range of Smart Home applications, as well as motors, amplifiers and pumps. Its integrated over-voltage protection and reverse current blocking features make it ideal for such applications, providing superior protection. Its high-side/low-side switching capabilities make it perfect for complex power distribution systems. Overall, RT9728AHGE is an ideal choice for high-power application that require over-voltage protection.
