XC8112/XC8113 Series
2ch Load switch IC with ideal diode function
ETR33022-001
■GENERAL DESCRIPTION
The XC8112/XC8113 series are 2ch load switch IC with ideal diode function. These ICs perform regulation control to ensure that their VOUT pin voltage is a value of VIN - 20mV, so they can suppress heat generation to a greater extent than general diodes.
When a voltage is applied at the VOUT pin and it becomes equal to or higher than VIN - 20mV, the driver FET will turn OFF. Furthermore, when the VOUT pin voltage becomes equal to or higher than VIN + 20mV, the IC’s internal power supply will switch from VIN to VOUT, which can prevent backflow current flowing from the VOUT pin through the parasitic diode to the VIN pin, while also interrupting current flowing from VIN to the IC.
