Torex Semiconductor XC8110/XC8111 Load Switch ICs

Torex Semiconductor XC8110/XC8111 Load Switch ICs reproduce ideal diodes and are equipped with chip enable (CE), over-current limit, inrush current limit, and thermal shutdown. These ICs perform regulation control to ensure that the VOUT pin voltage is a value of VIN - 20mV, so the device can suppress heat generation to a greater extent than general diodes.

When a voltage is applied at the VOUT pin and becomes equal to or higher than VIN -20mV, the driver FET will turn OFF. Furthermore, when the VOUT pin voltage equals or is higher than VIN +20mV, the IC’s internal power supply will switch from VIN to VOUT. This feature can prevent the backflow current from flowing from the VOUT pin through the parasitic diode to the VIN pin while also interrupting the current flowing from VIN to the IC. This device makes it possible to achieve an output voltage OR circuit and reduce battery consumption for backup purposes.

The Torex Semiconductor XC8110/XC8111 has been certified by the international standard IEC 62368-1, which defines safety requirements, and it is possible to simplify the single failure test of the subsequent circuits. By adopting the foldback method for over-current limiting, the short-circuit current can be suppressed to 50mA, and it can be used safely even in the event of a short-circuit. In addition, the thermal shutdown function can prevent the IC from being destroyed by heat.
