AiT Semiconductor Inc. www.ait-ic.com A4778 SWITCH 1.5A/ 2.1A/ 2.5A POWER SWITCH WITH FLAG DESCRIPTION FEATURES The A4778 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. Several protection functions include current limit and thermal shutdown to prevent catastrophic switch failure caused by increasing power dissipation when continuous heavy load or short circuit occur. A built-in 52mΩ P-channel MOSFET with true shutdown function to eliminate any reversed current flowing across the switch when the device is powered off. When the output voltage is higher than input voltage, the power switch will be turned off by the internal output reverse-voltage comparator.
