AAHS298B-07-4020A-V is one of the Power Management IC (PMIC) products in the Power Distribution Switches, Load Drivers series and provides superior protection and power switching for loads, such as batteries and electric motors. This PMIC IC includes auto-start and fault indication functions, and provides over-voltage, under-voltage, over-temperature and over-load protections, and realizes current limit control with constant current. Its key features include wide voltage range, fast response, high current protection, temperature protection and soft start.

As a member of the Power Distribution Switches, Load Drivers series, AAHS298B-07-4020A-V has a wide range of applications. First, it can be used as a battery charger power supply switch, as a system soft start switch, as a motor control switch, and as a power supply system switch. Secondly, this PMIC IC can also be used for other high-reliability power distribution applications, such as automotive, aviation, aerospace, handheld and telemetry systems.

The working principle of AAHS298B-07-4020A-V is based on its inner structure. This PMIC consists of power-on reset generator, over-voltage/ under-voltage protector, controller core circuits, logic circuitry and sensing and feedback circuitry. When the voltage of the output unit is lower than the allowable voltage, the power-on reset generator will raise the voltage back to its default level. When the output voltage is higher than the permissible voltage, the over-voltage/under-voltage protector will limit the current and the output will not be activated. The controller core circuit will control the other logic circuitry and ensure the device works under the specified conditions. The sensing and feedback circuitry senses the voltage or current fluctuations of the unit, and sends the signals to the logic circuits so that the device can keep running under the expected conditions.

In summary, AAHS298B-07-4020A-V is a PMIC IC of Power Distribution Switches, Load Drivers series, which is widely applied for powering batteries, motors and other high-reliability power distributions. And its working principle is based on the inner circuits, including power-on reset generator, over-voltage/under-voltage protector, controller core circuit, logic circuitry and sensing and feedback circuitry.
