Torex equips XC8110 and XC8111 with ideal diode function
Two load switch ICs from Torex are equipped with an ideal diode function. The XC8110 and XC8111 are equipped with functions including chip enable, over current limit, inrush current limit, and thermal shutdown.
In comparison to Schottky barrier diodes which are generally used to prevent backflow, the XC8110 and XC8111 the ideal diode function, the voltage is lowered to about 1/20 and achieves low loss, says Torex.
Despite the low VF of 20mV, the backflow current from V out to V in is 0, which is the ideal diode characteristic. With these features, the output OR circuit can be realised and battery consumption can be reduced.
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. The thermal shutdown function can prevent IC failure caused by heat.
The load switch ICs are supplied in low profile USP-6B06 packages with a height of just 0.33mm.
