AiT Semiconductor Inc. www.ait-ic.com A4788 POWER SWITCH 1.1A_2.1A_2.6A CURRENT LIMITED W/FLAG POWER SWITCH DESCRIPTION The A4788 is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. The A4788 is an integrated 80mΩ (TYP) power switch for self-powered and bus powered universal series bus (USB) applications. The A4788 is internally current limited and has thermal shutdown function to protect device and load from over-current damage. Thermal shutdown shuts off the output MOSFET and asserts the flag pin output if the die temperature exceeds 150°C until the die temperature drops to 130°C. The soft-start circuit can minimize inrush current in applications where highly capacitive loads are employed.
