BD2204GUL is a high-side switch IC designed for power supply selection in SD card applications. It features two built-in MOSFET circuits with a typical on-resistance of 120mOc, allowing for efficient power management. The device supports input voltage ranges of 2.7 to 4.5V for VIN1 and 1.2 to 2.4V for VIN2, with a continuous output current capability of 0.5A. The IC includes several protective features such as reverse-current protection, simultaneous-on prevention during power switching, and an output discharge circuit. It operates within a temperature range of -40 to +85¬8C and comes in a compact VCSP50L1 package measuring 1.50mm x 1.00mm x 0.55mm. This product is suitable for applications in digital cameras, digital video cameras, and SD card slots.
BD2204GUL is high side switch IC that has built-in 2circuits of MOSFET. Switch has achieved 120mO(Typ.) on-resistance. 3.3V power supply and 1.8Vpower supply for memory card can be selected by SEL terminal. Moreover, it has built-in simultaneous-on prevention function at power switching, reverse-current protection function to prevent reverse-current from output terminal to input terminal at power-off, and discharge circuit to discharge electricity in output terminal.
