BD2062FJ,BD2066FJ is a high side switch IC with over-current protection from ROHM for use in the power supply line of universal serial bus (USB). It has two channels of N-channel power MOSFET, and over-current detection circuit, thermal shutdown circuit, under-voltage lockout and soft-start circuit are built in.
The BD2062FJ and BD2066FJ are dual‑channel N‑MOS high‑side switch ICs designed for USB power‑supply lines in PCs, peripherals, and automotive accessories. They integrate over‑current detection, thermal shutdown, under‑voltage lockout, and reverse‑current protection.
Key features include an active‑high control input for the BD2066FJ, a current‑limit threshold of 2.4 A, a supply voltage range of 2.7 V to 5.5 V, and low standby current. The datasheet also provides absolute maximum ratings, typical electrical characteristics, and ordering details.
