Application

AAT4282AIPS-3-T1 is widely applied in various power supply designs, such as smartphones, tablets, portable devices, automotive electronics and lighting. It is a perfect choice for low-side and high-side power distribution, load drivers and low-side drivers.

Working Principle

AAT4282AIPS-3-T1 employs advanced bipolar CMOS technology to deliver high current drives. It has two pairs of switches attached to two power supplies, VIN and GND. When both switches are in the open position, no connection is established between input and output. When the control line is asserted, the switch low-side is activated and both switches are closed to make a connection between VIN and GND. The output thus provides constant power to the load. The device also features over-trap protection and over-current protection, ensuring reliable operation.
