The power switch device, including a controller, an undervoltage lockout circuit (UVLO) and an input voltage detection circuit, is configured to appropriately switch either a battery power or a public electricity to a portable electrical product. The power switch device further includes a thermal sense circuit, a current detection circuit and an output voltage detection circuit to provide over-high or over-low voltage protection, over-high current protection and over-high temperature protection.
