XC8110/XC8111 Series ETR33017-004a Load switch IC with ideal diode function ■GENERAL ☆Green Operation Compatible DESCRIPTION The XC8110/XC8111 series are load switch ICs that reproduce ideal diodes, and equipped with functions including chip enable (CE), over current limit, inrush current limit, and thermal shutdown. 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. This makes it possible to easily achieve an output voltage OR circuit, and to reduce battery consumption for backup purposes. This IC has been certified by the international standard IEC 62368-1 that 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. ■FEATURES ■APPLICATIONS Input Voltage Range Output Current ● Wearable devices ● Smart card devices ● IoT devices Stand-by Current Quiescent Current Reverse Bias Current Forward Voltage Over current limit ● OR Application ● Backup power supply ● Replacement from diode Short current Function ■TYPICAL APPLICATION CIRCUIT Diode / substitute for load switch Ideal Diode : VF=20mV VOU T VIN VIN 1.5V~6.0V CIN 0.1μF VOUT CL 0.1μF CE VSS Protective function Standard Operating Ambient Temperature Package 1.5V ~ 6.0V XC8110 : 500mA (VIN > 1.7V) XC8111 : 1000mA (VIN >2.0V) 0.65μA 3.6μA 0.8μA 20mV XC8110 : 850mA XC8111 : 1700mA 50mA Ideal diode function Reverse Protection Inrush current prevention Over current limit Thermal shutdown function IEC 62368-1:2018 Certified -40℃~ 105℃ WLP-4-02 (0.82 x 0.82 x 0.5mm) SOT-25 (2.8 x 2.9 x 1.3mm) USP-6B06 (1.5 x 1.8 x 0.33mm) ■TYPICAL PERFORMANCE CHARACTERISTICS OR circuit: backup circuit, etc. Forward characteristics Ideal Diode : VF=20mV VIN Main Power 5V CIN 0.1μF 0μA @ VIN
