ROHM's BD2220/1/4/5 Current Limit High-Side Switch ICs are high-side switches with a function of over-current protection used in the power supply line of a memory card slot. In the switch part, an N-channel MOSFET with low ON resistance has been integrated into the circuit. Moreover, a soft start function, an under-voltage lockout function, and an over-temperature protection function are integrated into the device as well. Typical applications include car audio, PLC, AC servo, set-top box, blood pressure monitor, DVR/DVS, home theater system, and various motor control applications.
