Product Description

1A Load Switch with Ideal Diode Function

The XC8111 is a 1A load switch IC with an ideal diode function that also features chip enable (CE), over current limit, inrush current limit and thermal shutdown.

Since this IC is equipped with an ideal diode function, compared to Schottky Barrier Diodes, which are generally used to prevent reverse current, the voltage corresponding to VF is lowered to about 1/20th and achieves low loss. Despite the low VF of 20 mV, the reverse current from VOUT to VIN is 0µA, which is exactly the ideal diode characteristic. With these features, an output OR circuit can be easily realized and the XC8111 can help reduce battery consumption in power back-up circuits.

The over current limit function uses constant-current limit and foldback current limit. By adopting the foldback method, the short-circuit current can be controlled to 50mA, allowing it to be used safely even in the event of a short-circuit. Also, the thermal shutdown function can prevent IC failure caused by heat.
