BD6528HFV
BD6529GUL
General Description
Key Specifications
BD6528HFV and BD6529GUL are high side switch IC
using an N-Channel Power MOSFET and used as a
power switch for memory card slot. This switch IC has
an ON-Resistance of 100mΩ for BD6529GUL and
110mΩ for BD6528HFV. Operations using low input
voltage (V IN ≥ 2.7V) are possible for various switch
applications. BD6528HFV is available in space-saving
HVSOF6 package.

When mounted on 70mm x 70mm x 1.6mm Glass-epoxy PCB, derate by 6.8mW /°C at Ta > 25°C
(Note 2)
When mounted on 50mm x 58mm x 1.75mm Glass-epoxy PCB, derate by 4.6mW /°C at Ta > 25°C
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated
over the absolute maximum ratings.
