One of the major advantages of load switch ICs is that they incorporate various functions, including inrush current limiting, auto discharge, overcurrent protection, thermal shutdown, undervoltage lockout, and reverse-current blocking. Therefore, load switch ICs help reduce the board area and improve system stability.
Figure 1 shows an example of a simple load switch composed of discrete devices. This circuit consists of a MOS pass transistor, a MOSFET gate driver, resistors, capacitors, and input and output smoothing capacitors. Figure 2 shows an application circuit for a load switch IC. In contrast to a load switch circuit composed of discrete devices, it consists of only three components: a load switch IC plus input and output smoothing capacitors.
