●Description
Power switch for memory card Slot (BD6528HFV, BD6529GUL) is a high side switch IC having one circuit of N-channel
Power MOSFET. This switch IC achieves ON resistance of 100mΩ with BD6529GUL; and 110mΩ with BD6528HFV.
Operations from low input voltage (VIN≦2.7V) is possible; made for use of various switch applications. BD6524HFV is
available in a space-saving HVSOF6 package. BD6529GUL is available in a space-saving VCSP-6 package.
●Features
1) Single channel of Low On-Resistance (Typ. = 100mΩ) N-channel MOSFET built in
2) 500mA output current
3) Low voltage switch capability
4) Soft-start function
5) Output discharge circuit
6) Reverse current flow blocking at switch off
7) HVSOF6 package for BD6528HFV
